Meet Our Residents

The Psychiatry Residency Program, sponsored by the UCR School of Medicine, began in July 2014 with four trainees. They were joined by a second group of four trainees in 2015.


Arrived in 2016.

Karla Lozano, M.D.

Karla Lozano

Dr. Karla Lozano grew up in sunny San Diego, California and received her undergraduate degree in human biology from the University of California, San Diego. She remained in Southern California throughout her medical training, at the UC Irvine School of Medicine, and received her M.B.A .from the UC Irvine Paul Merage School of Business.

Lozano became fascinated with mental illness and human behavior during medical school. Her passion for helping the underserved ultimately brought her to UC Riverside, as the program has strong ties to the community and encourages outreach projects. Furthermore, she valued the program’s county affiliation, culture of collaboration and highly supportive faculty and administration. Lozano’s interests include psychopharmacology, addiction, forensic and child psychiatry.

Khai Nguyen, M.D.

Khai NguyenDr. Khai Nguyen is a first-generation Vietnamese-American who grew up in San Jose, California. He attended UC Davis for his undergraduate studies and majored in neurobiology, physiology, and behavior. After college, he took time off to pursue his interest in health disparities research. He then stayed close to home when he chose to attend UC Davis for medical school. During his psychiatry rotations, Nguyen discovered his fascination with the human mind, the rewards of aiding patients in their recovery from mental illness, and the appreciation for the humanistic approach of psychiatry.

Nguyen decided on UC Riverside for his psychiatry residency training because of the program’s emphasis on community psychiatry, the passionate and supportive program leadership, and the flexibility residents have in developing their professional and personal lives. Nguyen’s interests include inpatient adult psychiatry, primary psychotic disorders, psychotherapy, and mindfulness.

Nathan Rogers, M.D.

Nathan RogersDr. Nathan Rogers graduated from Bates College with a double major in psychology and studio art before completing his medical education at nearby Maine Medical Center as part of Tufts University School of Medicine’s “Maine Track.” Nathan lived in California for several years between college and medical school, during which he raced as a competitive cyclist. Though his experiences in cycling led him to initially pursue orthopedic surgery, he found himself consistently more intrigued by the emotions and thoughts of patients than their physical injuries. After this revelation, the switch to psychiatry was a natural one.

UC Riverside appealed to Rogers due to its cooperative and respectful environment, its prioritization of community mental health, and its ideal location central to multiple cities, beaches, and mountains. His interests include mood and anxiety disorders, psychotherapy, and physician wellness.

Toshia Ann Yamaguchi, M.D.

Toshia YamaguchiDr. Toshia Ann Yamaguchi is originally from Fresno, California. She completed her undergraduate studies at UC Davis, majoring in biology with an emphasis in Evolution, ecology, and biodiversity and minoring in Spanish. Yamaguchi moved to Omaha, NE to attend Creighton University School of Medicine, where she studied the treatment of the mind, body, and soul. At Creighton, she realized her passion for helping patients with mental illness, one of the most underserved patient populations.

Yamaguchi found a cohort of faculty and residents with similar interests and a desire to serve patients at UC Riverside.  The program’s twenty-first century philosophy offers exciting opportunities and a culture that affords work-life balance.


Arrived in 2015.

Michael Ingram, M.D.

Michael IngramDr. Michael Ingram grew up in the suburbs of Sacramento, California and received his undergraduate degree in biochemistry at Occidental College in Los Angeles. After receiving his Master of Science in global medicine at the Keck School of Medicine of the University of Southern California, Ingram traveled across the country to Albany, New York where he attended Albany Medical College.

Although initially interested in surgery, Ingram quickly became fascinated with human behavior and fell in love with dissecting the human mind. He chose UCR for its receptive faculty and administration, its unique association with a county system, and its dedication to making mental health a priority in under served communities. Ingram’s interests include psychosomatic medicine, psychopharmacology, personality disorders, and bipolar disorder.

Monish Parmar, M.D.

Monish ParmarDr. Monish Parmar grew up in California, attended university at California State University, East Bay, and received his M.D. from the Medical College of Virginia in Richmond, Virginia.

Parmar chose UC Riverside because it genuinely encourages its residents to pursue their passions. Having worked with underserved populations in the past, Parmar is looking forward to continuing this service during the next four years.

Additionally, the collegial atmosphere between the faculty and residents at UCR was a major draw for Monish. The fact that Riverside is a stone’s throw away from some of the best beaches in the world was just a bonus for him.

Kazuo Omi, M.D.

Kazuo OmiDr. Kazuo Omi, M.D., or Kaz as he prefers to be called, grew up in Oakland, CA. He attended public school there all of the way through high school. He draws upon those formative years to better understand psychopathology.

Omi majored in biochemistry and molecular biology at UC Davis, then went to Washington University in St. Louis for medical school. He initially planned on a career as a pathologist and was part of the Medical Scientist Training Program (M.D./Ph.D. program), but during his years in lab he discovered that he preferred helping people to experimenting on mice.

Having earned his M.A. in immunology and pathology, as well as the ability to “speak science,” Omi hopes to bridge the gap between clinical and basic science departments as a member of the UCR psychiatry residency.

Evan Trager, M.D.

Evan TragerDr. Evan Trager originally hails from New Jersey and attended Swarthmore College, where he majored in biology with a focus on plant biology, using molecular tools to better understand cell wall construction. He graduated from the University of California, San Francisco School of Medicine.

Trager chose the UC Riverside psychiatry residency program because it was an ideal fit based on the program's strong commitment to social justice.

Trager has an interest in working with children, particularly in the juvenile justice and child welfare systems, and plans on pursuing fellowships in child and adolescent and forensic psychiatry.

She grew up in Pomona, CA and attended college at UCI.

Psychiatry was an interest of Patel’s that was reinforced in medical school, stimulated by an interest in mental illness presentations and how the field continues to advance as new treatments and studies develop.

His particular interests are in the field of child and development along with studying the co-occurrence of substance abuse in those with psychiatric conditions. He says the UCR Psychiatry Residency Program has been a great fit, with excellent faculty, staff and co-residents.
