Harjot Bath received a combined undergraduate/medical education at the Royal College of Surgeons Ireland and is currently interviewing for US residency programs in internal medicine. Dr. Harjot joined the CREST Network in the summer of 2019 to help with the analysis of pulmonary embolism patients in our MAPLE cohort. In addition to working with CREST, Harjot is involved in gastrointestinal research at UC Davis. 

 
Emergency department patients arriving with a clinic-based diagnosis have lower resource needs than those diagnosed in the emergency department.

Disha Bahl completed her first two years of undergraduate work at De Anza Community College in Cupertino, CA, before transferring to the University of California, Davis. She graduated in 2018 with a degree in genetics and genomics and is currently working for Roche Pharmaceuticals on nanopore sequencing. Her clinical research work with CREST focuses on acute pulmonary embolism patients who present with syncope, exploring the association of clot size with syncope and their correlation with adverse outcomes. She is working with Darcy Engelhart (below) and the CREST team to finish a syncope manuscript in early 2019.

Daphne D. Le joined CREST during her undergraduate years at University of California, Berkeley. She graduated in 2019. Her first project was an exploration of the management of stable wide-complex tachycardia in the prehospital setting, undertaken with Ashley, below. It was presented at a national meeting and was published in 2019. Daphne also led a case report on ibutilide-induced torsade de pointes. She is involved as well in our prospective TAFFY study on atrial fibrillation, contributing to a study on predictors of hospitalization, which she presented in 2018. The full manuscript will soon be submitted for peer-review.

Ashley S. Abraham began medical school at UC Davis, Sacramento, CA, in 2018. She graduated from the University of the Pacific in Stockton, with a major in bioengineering and a minor in social determinants of health. Her first project was a case report on Crohn disease, published in 2017, which has been followed by other case reports, e.g. on myocardial infarction and hair sliver. She worked with Daphne Le on pre-hospital ventricular tachycardia management. Ashley's project for 2019, with Alisha Othieno (below), was a retrospective analysis of intermediate-risk pulmonary embolism. She also contributed to our presyncope in PE study, which will soon be submitted for peer-review.
