Principal Investigator
Yunhee Choi-Kuaea, MSW
Clinical Research Specialist

Yunhee Choi-Kuaea earned her undergraduate and graduate degrees in social work from the University of Washington. Yunhee joined CIRCL and the Freedland Research Team in the winter of 2020, after spending three years as a clinical research coordinator (II) in the Cedars-Sinai Cancer Prevention and Control Program, leading efforts on patient recruitment, regulatory submissions and biospecimen management. Within CIRCL, Yunhee will be leading and managing communication efforts with regulatory bodies, handling tissue and data transfers and helping to grow the existing portfolio of projects.

Gloria Cecilia Galván, PhD
Postdoctoral Scientist

Gloria Cecilia Galván, PhD, earned her undergraduate and graduate degrees from the University of Texas (UT) at Austin. Her dissertation work focused on the role of obesity in modulating the prostate tumor microenvironment by programming immune cells into a tumor-associated phenotype. During her doctoral studies, Galván also completed three summer clinical rotation programs including General Oncology and Phase I Clinical Trials at the START Center for Cancer Care, and Urology at the Mays Cancer Center at UT Health San Antonio MD Anderson Cancer Center. Due to her interest in translational research and in the role of diet and lifestyle in prostate cancer, she joined the Freedland Laboratory as a postdoctoral scientist where she is leading a study to test the effects of carbohydrate quantity and quality on prostate cancer growth. Additionally, Galván is working on deciphering the impact of an altered cholesterol metabolism on prostate cancer growth and progression.

Alexandra Mack, MPH, MPL
Program Development Administrator

Alexandra Mack is a food professional with public health, academic, e-commerce and retail experience, and a history of managing teams for food, cooking, and nutrition-related organizations. Her expertise includes project management, multidisciplinary communications, teambuilding, financial analysis and strategy development.

Patrick Tamukong, MD, PhD
Postdoctoral Fellow
Adriana Vidal, PhD
Research Scientist I

Adriana Vidal, PhD, earned her bachelor's degrees and doctorate in biology from the Universidad Nacional del Sur, Argentina, and proceeded to do postdoctoral studies at Dartmouth Medical School. Vidal focuses on environmental exposures that may influence cancer racial disparities, with recent projects aimed at understanding how inflammation caused by infectious agents and dietary carcinogens may in part be responsible for disproportionally higher prostate and cervical cancer incidence and mortality rates in African Americans.
