Founding Member of the MAPS Leadership Program


The MAPS Leadership Team




(Director of MAPS 2016 – present)

(Co-Director 2009 – 2016)

My name is Cait Walsh and I am the Director of MAPS.  I spend a lot of time with quality and safety related projects.  I love my job because I am intimately involved in creating a safe environment for patients.  I have worked in the UC hospital system (UCSF and UCLA) for 25 years.  I have my Masters Degree from UCSF in Geriatrics (Geriatric Nurse Practitioner).  The MAPS program was a perfect fit for me.  The safety issues (hand hygiene, two patient ID when giving meds and unlabeled and unattended syringes) the MAPS Program tracks help improve overall quality and safety for UCLA Ronald Reagan Hospital.  I also love working with students.  My free time is spent with my husband (a UCLA surgeon) and my two great kids.  I love outdoor activities:  hiking and sailing.  I also love art and dance.


(Co-Director of MAPS 2009 – 2016)

My name is Petra Fritz and I was Co- Director of MAPS until Spring, 2016. About 15 years ago, I came from Germany to the US. I studied nursing in Germany. I wanted to learn more about nursing here in the US and so I started as a volunteer at UCLA.  After I took NCLEX, I worked for two years in Tucson/Arizona in a Trauma ICU. Tucson was a little too hot for me so I came back to California and UCLA.  I worked as a nurse in the Neuro/ Trauma ICU until I transferred to the Department of Accreditation where I work as the Accreditation Coordinator with Cait Walsh. Patient safety is an important issue for the Department of Accreditation. To work with the MAPS program and all the students involved, is perfect for me. The MAPS program helps to make changes in the hospital. These changes will, over time, make our patients safer. I also see the students involved in the MAPS program change. As an example, the awareness and the importance of hand washing is more present in all of our MAPS volunteers. I can see that the volunteers change their habits of hand washing and it will not stop at our hospital door. The volunteers will bring their knowledge home. They will share the information and more changes will happen. I am very excited to be a part of this fantastic program.

Active Intern Coordinators (2016):

Margaret Huang


Hello everyone! My name is Margaret Huang and I am currently a third year at UCLA,  majoring in Psychobiology. I dreamed of being a doctor one day, but I had no idea where to start. MAPS has given me an excellent opportunity to explore so much within the hospital. I was able to observe what different health care personnel do and see different units and departments in the hospital. Today, I am focusing on my goal of becoming a physician. In my free time, I enjoy exploring foodie places, taking pictures of food, and hanging out with my family and friends. As your intern coordinator for next year, I will be responsible for assigning monthly units for volunteers and recruiting new members for the organization (AKA Outreach). I am very easy to talk to, so let me know if you have any questions!

Codi Young


Hi everyone! I’m Codi Young, a MAPS Intern for 2016-2017. I am from the LA area, specifically the San Gabriel Valley (SGV)! (It’s a great place for yummy Asian food!) Coming to UCLA, I knew I wanted to pursue a career in the health care field, but I was at a loss at where to begin exploring the different career paths. Joining MAPS during my first year has been a complete eye-opener: I was able to observe different health care professionals, explore the different units in a hospital, and observe interactions between staff and patients. From MAPS, I discovered and developed my interest in Medicine and Public Health. As your intern coordinator for next year, I will be in charge of communications – I answer all emails, update the MAPS website, and plan general meetings and training sessions. Feel free to email us at – we are always happy to help you!

Jenna Fox


Hi! My name is Jenna Fox, and I am one of the MAPS interns for 2016-2017. I lead the MAPS branch at Santa Monica Hospital, as well as the Fall Ambassador Program at Ronald Reagan. My decision to join MAPS during my 2nd year at UCLA has proven to be eye-opening, and has greatly shaped my career aspirations. When I started college, I was interested in the healthcare field, but I was unsure of which career path I wanted to take. I was initially drawn to MAPS because it allows volunteers to observe patients and shadow physicians in so many parts of the hospital. Now that I am a senior, I can attest that MAPS has provided me with incomparable knowledge about the numerous healthcare professions, and has even allowed me to make connections with professionals in my field of interest. As an intern, I’m looking forward to expanding our team in Santa Monica and adding new members to our Fall Ambassador Program. In my free time, I love exploring new places in LA and spending time with friends and family.

Archana Reddy

Archana Reddy Bio

Hey everyone! My name is Archana Reddy and I am currently a third year at UCLA double majoring in Biology and Sociology. MAPS thus far has been such a great experience, allowing me to explore all avenues of an institution as large the UCLA Health System while simultaneously keeping the hospital a safer place. My interests lie both in Medicine and Public Heath and have only strengthened and garnered motivation from my involvements in the MAPS volunteer program. In my free time I enjoy doing yoga, exploring new foodie places, and spending time with friends/family. As your intern coordinator for next year I will be in charge of assigning units for volunteers and recruitment for the program (outreach). I really look forward to meeting you all, so please feel free to say hello!

Melinda Ng

Melinda Ng bio

Hello everyone! I’m Melinda Ng and I’m a third year majoring in Biochemistry. I’m from the Bay Area and some of my interests include swimming, running, and baking. When I first came to UCLA, I was unsure of what volunteer organizations I should be part of. I decided to join MAPS because I saw the various opportunities that it could provide for me. I’m so glad I joined MAPS because through this organization, I was able to have direct exposure to two different hospitals, Ronald Reagan Medical Center and Santa Monica Hospital, which give me a few different perspectives on healthcare from healthcare personnel.  From shadowing physicians to working with nurses to improve a patient’s experience, I have grown a lot. Now, I want to give back what I learned and mentor new volunteers. As next year’s intern coordinator, I will be in charge of communications and answer your emails. Don’t hesitate to email if you have any questions. I’m always here to help you.

Sean Bentley 

Sean Bentley

Hey everybody! My name is Sean Bentley and I’m graduating this fall in Psychobiology. I’m from San Diego and in my free time I like to play tennis, surf, and go to concerts. When I first came to UCLA, I had no idea what career direction I wanted to go in. Thanks to the great exposure I’ve gained from the M.A.P.S. program to healthcare and to the lives of doctors and nurses, I became interested in a career practicing medicine. This program has giving me so many great opportunities to further explore this interest. I have gained so much valuable shadowing experience from the program, and it has strengthened my passion and resolve to become a future doctor myself. As your intern in this coming year I will be in charge of expanding the M.A.P.S. program further at UCLA’s Santa Monica hospital— working on gaining access to more hospital floors as well as recruiting and training more volunteers for that location. I look forward to working with you all!

Jonathan Keyes

Jonathan Keyes Bio

Hi guys! My name is Jonathan Keyes and I am a third year majoring in physiological science while minoring in biomedical research. I came to UCLA unsure of what to do but through MAPS, I was exposed to the hospital environment and the healthcare field. Now, I have the goal of becoming a physician in the future so that I can achieve something amazing for this world. As a Pre-Med, I am constantly bombarded with work. Nonetheless, I still manage to maintain a decent amount of life by going hiking, hanging out with friends, running, going out with my family, and watching TV shows. As your intern coordinator for this year, I am responsible for your monthly assignments and outreach (aka. recruitment). So if you have any friends who are Pre-Meds, tell them about MAPS! I’m easy to talk to so if you have any questions (even things that are not MAPS related), feel free to ask away!

Kara Tanaka

Tanaka 2014MAPS is an incredible volunteering opportunity that is open to students from all schools – they welcomed me, a post-baccalaureate premedical student at USC, into the UCLA family, as they do with all their volunteers. Being a part of MAPS is great for all academic disciplines – volunteers get a chance to experience nearly all of the hospital units during their rotations and they can see if the hospital is a place where they can build a future. MAPS has been expanding, and last year we began to implement rotations at Santa Monica Hospital to compliment to our established program at UCLA Ronald Reagan. My job as an intern is to continue growing the Santa Monica division and to work with my fellow interns to invite guest speakers and provide valuable educational resources to our volunteers about hospital safety and patient care.

Dan Wayer

DW Bio Picture

Hey everyone! My name is Dan Wayer and I’m currently a third year neuroscience major. Prior to coming to UCLA I lived my entire life in the suburbs Muskego, WI. My interest in neuroscience first developed during my AP Psychology class in high school, my first real exposure to the workings of the brain, and it has only strengthened ever since. Outside of school, I really enjoy watching soccer and TV shows, as well as going to the gym. Among all of the new things I have experienced here in California, I am most impressed with the amount of amazing people I have met (although the weather is a plus too). This is definitely true of my experience in the MAPS program, as it has allowed me to connect with so many people that I would have never thought I could have prior to joining the program. MAPS has given me the opportunity to not only experience what it’s like in all of the departments of the hospital, but also to connect with hospital staff of all levels and gain insight into their work. This is all happening while you are making the hospital a safer place, and is one of the main reasons I have enjoyed working in the MAPS program. If you guys ever have any questions for me, please direct them to the UCLA MAPS gmail account, as I am the one who is the one overseeing this email.

Hanning Xing

Hanning Pic

Hi everyone! I’m Hanning Xing, and I am currently a second year Computational & Systems Biology major. I come from Arcadia, CA—the land of the peacocks and amazing boba. (If you are ever in need of some savory Asian food, go visit!) I came into UCLA as an Electrical Engineering major, but I soon found out that I had no interest in it. I wanted to be a doctor one day. I had always dreamt of donning that white coat and saving lives. But I had no idea where to start, let alone what a hospital was like at all. One of the first things I did was to join MAPS—and it has given me an unparalleled experience within the hospital. I’ve learned so much about the hospital and its staff, including the dozens of different professions that make the hospital run smoothly every day. I love being a part of the great work that MAPS does in promoting patient safety. And now as an intern, I am definitely excited to be more involved in MAPS and to further expand this amazing program.

Jumana Aljumaily
meeeeeeHello all, I’m Jumana Aljumaily and I am very excited to be one of the MAPS Interns for the upcoming year!  I am a third year undergraduate studying Anthropology and Neuroscience. I was initially drawn to Anthropology for its combination of human culture/language and biology because I feel that both aspects are interrelated extensively and are worth studying.  Through my research experience studying traumatic brain injuries and biomarkers, I quickly became intrigued in Neuroscience as well.  I am very passionate about serving my community and volunteering abroad and hope to continue that in my future career.  In my spare time, I love to hang out with my friends, watch Modern Family, and catch the occasional spin class.  I grew up as an only child in a small town in Southern California called Hemet.  Needless to say, coming to UCLA was a huge leap.  I am so grateful to be here and have remarkable opportunities at my footsteps.  A prime example being the MAPS program, which I have been involved with since November 2010.  I joined primarily to become more familiar with how a hospital (especially an acclaimed one like the Ronald Reagan Medical Center) operates on any given unit and also to gauge my passion for becoming a physician.  MAPS has allowed me to see essentially every unit in the hospital in addition to physician shadowing and has given me the stepping stone to my future in medicine.

David Perlman

Hello everyone! My name is David Perlman and I am one of the new MAPS Intern Coordinators. I am a third year psychobiology major at UCLA. I fell in love with psychology because of my AP Psych class in high school; and this pasion has only gown with time.  I grew up in San Diego with one younger brother. I love UCLA because of all the great people I have met and all of the awesome opportunities that UCLA has to offer. I have been volunteering with MAPS since January 2011, and this program has given me some of the most rewarding experiences of my entire life. I started volunteering in the program with the hopes of gaining intimate knowledge about the inner workings of one of the best hospitals in the world. MAPS has gone above and beyond this expectation. I am proud of this program and how it has grown so far, and I know that the other new interns and I will work our hardest to maintain this level of expansion to increase the amount of opportunities it has to offer to our volunteers. Don’t be afraid to e-mail me about anything, and I can’t wait to see the changes that the MAPS family will make next!

Shaylyn Stanley

Hello! My name is Shaylyn Stanley and I’m currently a third year Psychobiology major. I grew up in the San Fernando Valley and went to high school in La Canada near Pasadena (right by the Rose Bowl). When I first came to UCLA, I knew that I liked science but truthfully had no idea what field I wanted to go into. After much exploring of different classes and switching majors four times, I found that my true interest was in the life sciences and started to really see myself going into medicine. I didn’t know much the field so I thought it would be a great idea to volunteer at the hospital and that’s when I found MAPS! I’m so thankful for the opportunities it’s given me. Though I’m still not entirely sure medical school is the life for me, the program has given me great insight and has opened more possibilities of medical careers outside of just becoming a doctor! Now as an Intern Coordinator I’m looking forward to working on expanding the program even more and seeing what we can all accomplish. If you have any questions don’t be afraid to ask us! This is a great group of people you should be excited to be a part of!

Halina Yee

Selena Zhou


Hello! My name is Selena Zhou and I am a third year Physiological Science major, Political Science minor at UCLA. I am from Alhambra, California in the suburbs of Los Angeles. I love musicals, I love food, and I love traveling (though I am a LA girl through and through). I came to UCLA knowing I wanted a career in the health care field but not knowing exactly what I wanted to do. MAPS is amazing and unlike any other program in that it allows you to observe what all the different health care personnel do exactly. And you do this while gathering patient safety data that may have a huge impact on common clinical processes done in hospitals. Today, I am focusing on my dream of becoming a physician. That means I am buried in coursework and extracurriculars, like all pre-meds here really. But I commit myself to MAPS because it is one of those programs that is truly doing something amazing for the world and I just love being a part of that.

Prior Interns (2011-2012)

Michael Arias


Hello everyone! My name is Michael Arias, and I am a previous MAPS Intern Coordinator (2011-2013). I graduated as a Biology major from UCLA in March 2013, and in May 2016, I also graduated Magna Cum Laude from the USC Keck School of Medicine’s MPH Program under the Biostatistics and Epidemiology track. Currently, I am a medical student at New Mexico State University’s Burrell College of Osteopathic Medicine.

I was fortunate to attend graduate school at USC on a full tuition scholarship from the United States Army Reserves, which commissioned me as a 2nd Lieutenant officer in Medical Services upon graduation of my Master’s degree in May 2016. My responsibilities in the Army Reserves, like MAPS, include evaluating the quality of patient care and developing criteria for these evaluations, all in accordance with the Joint Commission. My job description as an officer in the Army Medical Department is also very similar to MAPS in that it involves developing hygiene standards and promoting policies for the prevention of disease.

MAPS has played a huge part in getting me to where I am today. It was because of my time as a volunteer in MAPS that I discovered my interest in public health, which led me to pursue the USC Master’s in Public Health program. Also, the leadership skills I learned from Cait and Petra in the MAPS Leadership meetings as Intern Coordinator allowed me to have success in the leadership courses I completed with the USC Army ROTC Program, such that I graduated as the top Cadet from USC’s Trojan Battalion. MAPS also allowed me to find preventive medicine jobs within the army that I know I will perform with success due to their striking similarities to the responsibilities I had as Intern Coordinator. Finally, if it were not for my internship with MAPS and working so closely with Cait and Petra, I do not think I would have made it into medical school – MAPS was truly a transformative experience in introducing me to my love for health care and preparing me for a career in this challenging but rewarding field. For all of these reasons and more, I am thankful for my years as both a MAPS volunteer and Intern Coordinator!
