Please Welcome Our New Physicians

Galen Garcia, MD​

Dr. Garcia is a native Tucsonan who has recently returned from New England. He obtained his dual bachelors degree in Chemistry and Biochemistry from the U of A and then continued on to medical school at UA Tucson.   He completed his Anesthesiology residency at Tufts University College of Medicine, Boston, MA and then completed a fellowship in Pediatric Anesthesia at Harvard University - Boston Children's Hospital. While living in Boston, he and his wife became parents to two daughters, Pippa and Gemma. In his spare time, he likes to run, bike, and cook - specializing in meat. His most recent endeavor is to dry age his own bone–in rib roast. His favorite activity is to travel with his family.



Michelle DeCosta, MD​, MBA

Michelle DaCosta, MD is originally from Dayton, Ohio.  She graduated from the University of Michigan with majors in biopsychology and cognitive science and a minor in biology. She attended Wright State University BSOM for medical school in Dayton, Ohio, did her internship at the Jewish Hospital of Cincinnati and completed her residency in anesthesiology at the Allegheny Health Network in Pittsburgh, PA.  She did a pediatric anesthesiology fellowship at Washington University and a pediatric cardiac and adult cardiac anesthesiology fellowships at Children’s Healthcare of Atlanta and Emory University.  Dr. DaCosta is board certified in anesthesiology, pediatric anesthesiology, and advanced perioperative TEE.  She also completed her MBA with a healthcare administration certificate from the University of Cincinnati Lindner College of Business. Dr. DaCosta is interested in global health and has traveled to Haiti and Bangladesh for pediatric                                              anesthesiology mission trips.  She enjoys playing tennis, soccer, and riding her bike. She loves to travel, and enjoys concerts, musicals, the orchestra, and the                                              theatre.


Allison Thoeny, MD​

Allison Thoeny joins the faculty as a pediatric anesthesiologist. As an Arizona native and life-long Wildcat, she is thrilled to be returning home to her alma mater (Class of 2013) at the University of Arizona College of Medicine. After completing her internship in Internal Medicine at the University of Arizona Affiliated Hospitals, she moved to California to complete her residency training at the University of California San Francisco, followed by a fellowship in pediatric anesthesiology at Children's Hospital Los Angeles. Some of her professional areas of interest include pediatric anesthetic neurotoxicity, medical education, and career development of women in anesthesia. She and her husband of 10 years are enjoying being back in the Sonoran Desert, taking in the land of Saguaros, plentiful wildlife, and breath-taking sunsets. When not working you may find her in the swimming pool or taking a dance class; never far                                                 from her side is their dog of 14 years, a very affectionate chihuahua-mini dachshund mix.

University of Arizona’s College of Medicine 2018 Founders Day Award

float: left; padding-right: 50px;

Celebrating the Founders Day Award are: Mohab Ibrahim MD,
Amol Patwardhen MD, Todd Vanderah PhD, and Randal O. Dull, MD PhD. PhD.

Todd W. Vanderah, Ph.D, Professor and Chair of Pharmacology and Professor of Anesthesiology was the University of Arizona’s College of Medicine 2018 Founders Day Award recipient. On an annual basis, the UA-COM recognizes the anniversary of the medical school’s opening by recognizing a faculty member whose career and scientific accomplishments have been exemplary. Dr. Vanderah presented a seminar entitled “A painful yet rewarding journey” where he described his 20+ years in pain research and the many important discoveries his laboratory has made.  Dr. Vanderah has over 20 years of continuous NIH funding and boasts an H-index of 62. His work has centered on understanding neural networks associated with pain pathways and opioid reward and tolerance. His current work involves testing novel agonists that interrupt the opioid reward mechanism(s) and which have the promise to reduce opioid addiction. Dr. Vanderah is currently mentor to Anesthesiology faculty Drs. Amol Patwardhan, MD and Mohab Ibrahim, MD who both received NIH grants in July of 2018. It is our distinct pleasure and honor to have Dr. Vanderah as a Professor of Anesthesiology and we look forward to his continued collaboration and success.



University of Anesthesiology Faculty Garner NIH Funding

University of Arizona Anesthesiology faculty Amol Patwardhan, MD, PhD and Mohab Ibrahim, MD, PhD both received notice of awards from NIH this month. Dr. Patwardhan, MD, PhD received an NIH-K08 Mentored Clinician-Scientist Award while Dr. Ibrahim, MD PhD was awarded an RO1. This marks the first time in many years that the Department of Anesthesiology has NIH funding.  The new Department Chair Randal Dull, MD, PHD said this is just the start we need towards rebuilding Anesthesiology into a premier academic department.

Amol and Mohab represent the kind of success that can be achieved at the UA when clinician-scientists team up with outstanding basic scientists to tackle patient-related issues. Both investigators work closely with members of the Department of Pharmacology including Chairman Todd Vanderah, PhD; Frank Porreca, PhD, and Rajesh Khanna, PhD and Philip Malan, MD, PhD. (see https://pharmacology.arizona.edu/faculty). “This mentoring team has been a tremendous help for both Amol and Mohab and I am grateful for their dedication towards the development of these outstanding faculty members” said Dr. Dull.  In fact, the depth of expertise on this mentoring team could not be found in most major research universities and is testament to the strength of our basic science department. The Departments of Anesthesiology and Pharmacology have enjoyed close ties for many years and we look forward to developing this collaboration into other clinically-relevant areas and leveraging this success in the recruitment of NIH-funded faculty into both departments.

Dr. Patwardhan is an interventional pain physician, anesthesiologist and pharmacologist who studies novel mechanisms for inhibiting spinal pain transmission. His grant will assess the molecular mechanism  by which contulakin-G (CGX), a peptide derived from snail venom, produces analgesia but without adversely affecting motor neuron function. Developing novel therapeutic compounds that are not related to opioids represent a huge opportunity in anesthesiology and neuro-pharmacology. Dr. Patwardhan and his team have proposed several hypotheses regarding the sites of action for CGX and plan to characterize the receptors and channels that are inhibited by CGX. A second major aspect of these studies is the observation that CGX does not result in tolerance, a common and rate limiting aspect of many pain medications. Characterizing how to avoid the development of tolerance for analgesics opens the possibility of improving the efficacy of existing analgesic drugs. We look forward to following the success of this very talented team of scientists.

Dr. Ibrahim is also an interventional pain physician, anesthesiologist and pharmacologist. His research focuses on the treatment of chronic pain in patients with HIV. Antiretroviral therapy, the mainstay of HIV treatment, is associated with an increased incidence of chronic pain. Dr. Ibrahim and his research team completed a pilot study to determine if different wavelengths of light have specific analgesic effect. They found that rats with chronic, HIV-related neuropathic pain experienced analgesia when exposed to green light in the range of 525 nm for 8 hours per day. In this 5-year NIH funded study, Dr. Ibrahim will study the mechanisms by which green light induces analgesia. Specifically, they will characterize neuroinflammatory pathways in the brain and spinal cord to understand how green light reduces neuropathic pain. Non-pharmacological therapies hold great promise for the treatment of chronic pain as they are cost-effective, devoid of most drug-related side effects and economically scalable for use in medically challenged areas, cultures and countries. 


Congratulations to these truly outstanding clinician-scientists and educators!
