    Michael Clamp, MD, MA was born and raised in Florida. He studied Behavioral Neuroscience at the University of Florida and conducted research related to macular degeneration at the Whitney Laboratory in St. Augustine, FL. An avid outdoorsman, he spent many a weekend guiding rock climbing trips for the University’s Travel Recreation Program. After his undergraduate years he worked on a sailboat in the Caribbean and backpacked throughout Central America. He spent two years studying Western Classics at St. John’s College in Santa Fe, NM, while working as a tech and fundus photographer for a local retina specialist. He returned to the University of Florida for medical school where he enjoyed electives in medical humanities and participated in medical missions to Peru and Nicaragua.

    Dr. Clamp was drawn to CPMC’s Ophthalmology program because of the supportive atmosphere, exceptional clinical training and ample international training opportunities. He took advantage of the time afforded by CPMC’s staggered start to get married, study macular hole formation, and work at a surf camp in Indonesia. During his internship at Shands Hospital Dr. Clamp received a teaching award from the medical students and he looks forward to sharing ophthalmology with students and colleagues throughout his career.

    Adrian Dokey, MD grew up in Sacramento, CA and earned his bachelor's degree in Molecular and Cell Biology from the University of California, Berkeley. There, he enjoyed participating in various intramural sports, playing music, tutoring high school students, and conducting research on patterns of disease transmission in primates. He went on to earn a medical degree from Johns Hopkins University, where he found exceptional mentors who helped guide him onto a career path toward ophthalmology.

    Before starting at CPMC, Adrian completed a preliminary year in internal medicine at Kaiser Permanente in San Francisco. For him, the biggest draws of CPMC were the exceptional medical/surgical training and the truly unique culture that has built a family of residents who are both highly accomplished but still easygoing and genuinely invested in each other's success. Outside of medicine, Adrian continues to enjoy playing basketball and tennis, playing and listening to music of all genres, and exploring the many different parts of the San Francisco Bay Area.

He attended Tulane University, graduating summa cum laude with a Bachelor of Science in Chemical Engineering and Cell and Molecular Biology. He returned home to attend the University of New Mexico School of Medicine and completed his internship in internal medicine at UPMC Presbyterian-Montefiore Hospital in Pittsburgh, Pennsylvania.

    He is excited to join the CPMC Department of Ophthalmology and experience diverse training opportunities in many practice settings. During his free time, he enjoys homebrewing, cooking, running, water sports, and skiing.


    Derek Huang, MD is a California native, originally from Los Angeles. He attended Stanford University, where he majored in Biology and Economics.

Outside of medicine, Dr. Huang enjoys being a Lakers fan, traveling, finding new places to eat, and exercising.

    Rachelle Rebong, MD was born in the Philippines but grew up in Daly City, CA. She received her undergraduate degree in Biology from the University of San Francisco and her medical degree from Duke University. There she found fantastic mentors who introduced her to the field of ophthalmology. She was instantly drawn to the field’s mix of clinical and surgical opportunities and the chance to make a significant impact on patients’ daily lives.

    She completed her intern year at CPMC’s Department of Internal Medicine and is very excited to continue her residency at CPMC’s Department of Ophthalmology. She loves the program’s supportive environment, its breadth of clinical training, and its commitment to resident education. In her free time she enjoys traveling, reading, running, and hiking.

    Jill Rotruck, MD was raised in West Virginia. She received undergraduate degrees in Biology and Music from Shepherd University in Shepherdstown, WV and her MD at West Virginia University in Morgantown, WV. Following graduation from medical school, Dr. Rotruck completed a Transitional Year at WVU. She is very excited to be training in ophthalmology at CPMC because of its supportive and knowledgeable faculty, dedicated and fun co-residents, and unique educational opportunities. The staggered start allowed her to work on her Spanish and work and learn in an international setting at clinics and hospitals in Nicaragua as well as with Unite for Sight in Honduras. In her free time, she enjoys traveling, hiking, singing, eating dessert, and finding completely random things to do in San Francisco.

    Aileen Sy, MD, grew up in Southern California, and received her undergraduate degree from Harvard University in Biochemical Sciences. She returned to California for her medical degree at University of California, San Francisco. It was during her medical training that Dr. Sy had her first experiences with ophthalmology, here at CPMC, and was so impressed by the field that she decided to take a year to pursue a research fellowship in ophthalmology. During this time, she worked with outstanding mentors at the Proctor Foundation at UCSF on international clinical trials investigating treatments for fungal, bacterial and viral corneal infections. While the foundation of Dr. Sy's interest in ophthalmology lies in its unique combination of critical clinical thinking with surgery to profoundly impact patients’ lives, experiencing the presence of ophthalmology in the international community and the innovative nature of the field solidified Dr. Sy's passion for ophthalmology.

    She is thrilled to complete her training at CPMC where strong clinical and surgical training is achieved in a supportive and collegial environment, and where opportunities to serve the underserved both locally and internationally abound. Outside of medicine, Dr. Sy enjoys playing the violin and piano, karaoke, and exploring new cuisines both in the city and at home in her kitchen.
