Susana Ortiz Urda, PI 

Dr. Susana Ortiz-Urda, MD, PhD, MBA, co-director of the UCSF Melanoma Center, treats patients with early and advanced melanoma. Her lab has broad expertise in human models of epithelial neoplasia and melanoma. She studies in-depth cancer signaling to identify novel transcripts, their functions, and the factors that promote resistance to drugs and/or cancer progression via transcriptome (RNA-Seq) to capture the implicated coding and non-coding elements in this process. These findings might serve as key biomarkers and/or new targets for therapeutics in melanoma.

Dr. Ortiz-Urda earned a medical degree and doctorate at the University of Vienna in Austria. She completed a residency in dermatology and a postdoctoral fellowship in epithelial biology, both at Stanford University, followed by a cutaneous oncology fellowship in dermatology at UCSF and an MBA at NYU. She is a member of the American Academy of Dermatology, the Austrian Society of Dermatology and Venerology, and the Dermatology Foundation. Dr. Ortiz-Urda has received several awards, including the Kardinal-Innitzer Award for Outstanding Science in Dermatology and the Unilever Award from the Austrian Society for Dermatology and Venerology. She is an Associate Professor of Dermatology at UCSF.



Valentin Feichtenschlager, MD


Dr. Valentin Feichtenschlager's expertise lies in the research of long non-coding RNA (lncRNA) biology and MAPK-signaling in cancer, with a focus on melanoma. His journey into dermatological research began in Vienna, where he collaborated with Drs. Christian Posch and Igor Vujic in clinical research projects as a member of the research team at the Rudolfstiftung Hospital in Vienna, under the guidance of his mentor, Professor Klemens Rappersberger.

In 2017, he continued to build on his laboratory experience and scientific knowledge by joining the Ortiz Lab at UCSF. His research led to the identification and characterization of the lncRNA “T-RECS”, which is overexpressed in melanoma cells and essential for their survival.


James Zheng, MD

 

Dr. James Zheng completed his medical education at the University of California-San Francisco School of Medicine in 2023 and is currently a resident in Otolaryngology-Head and Neck Surgery at Houston Methodist Hospital. Prior to attending medical school, James volunteered in the Ortiz lab and maintains an ongoing collaboration in research while managing his residency responsibilities.


Ciara Callanan, MS1

 

Ms. Callanan is a current medical student at the University of Illinois. She began working with the Ortiz lab as an undergraduate student at UC Berkeley in 2018. Her dedication to the lab and dermatology research has allowed her to develop a strong understanding of melanoma, and she has been able to apply that here at the Ortiz Lab by greatly contributing to our cell culture and in vitro experiments. 

 


Albert Lee, MS1

 

Albert Lee is pursuing his MD at UCSD School of Medicine after completing degrees in Immunology and Economics at UC Berkeley. He is passionate about improving cancer health outcomes and his research experience includes wet lab melanoma, clinical hematology-oncology, and health economics research. 

 

 
Dasha Hohlova, BS

 

Ms. Hohlova is a dedicated researcher currently pursuing her Master's degree in Science at the University of San Francisco. With a profound background in melanoma research cultivated during her undergraduate studies at the same institution, she brings a wealth of knowledge and expertise to her work. Her commitment to advancing our understanding of melanoma pathology and developing innovative treatment approaches reflects her passion for making a meaningful impact in the field of cancer research.
