Students

Emily Wang

Emily is a sophomore in the College of Arts and Sciences at Vanderbilt University.  She is majoring in Neuroscience and minoring in Corporate Strategies.  She hopes to pursue a career in medicine and serve through Army ROTC.  Originally from New Jersey, she volunteers as a First Aider on the local rescue squad when she is at home.  Some of her hobbies include playing the piano and violin, playing sports (lacrosse, soccer, ultimate Frisbee) and traveling.
Her summer project with PDSR is focused on pain in the post anesthesia care unit (PACU) to assess the variability of providers.  The goal of this study is to understand how documentation of pain varies among providers and if this impacts care downstream.  Pain scores stratified by surgery type across a variety of post-anesthesia care unit (PACU) providers will be examined.  The frequency of pain score documentation, mean score upon entry into and discharge from the PACU, and other variables will be compared.

Molly Cowan

Molly is a junior majoring in Mechanical Engineering and minoring in Mathematics at Vanderbilt University.  Her work within PDSR in conjunction with the CRISS group has focused on the identification of technology-related events during operative procedures.  Using SQL, she also works on various data requests for research projects.  Molly is originally from Cincinnati, OH and has interests in football, soccer, and movies.  She enjoys volunteering at Vanderbilt Children's Hosptial and with individuals with intellectual disabilities.

Monika Jering

Monika is in her final year of medical school at the Ludwig Maximilians University Munich, Germany.  She joined the PDSR group to conduct the research for her doctoral dissertation.  Her project focuses on the intraoperative evaluation of the surgical Apgar Score.  The surgical Apgar Score is a tool to predict a patient's 30-day morbidity and mortality after undergoing surgery.  In her free time Monika enjoys traveling and exploring foreign cultures.  She also works with newly arrived immigrants in Germany as a cultural ambassador and medical volunteer.

Aneesh Goel

Aneesh is currently a second year medical student at the University of Virginia School of Medicine.  His work with the PDSR group has focused on identifying previously undetected renal failure and myocardial infarctions in postoperative patients.  He is interested in a career in anesthesiology but is keeping an open mind before his clerkship year.  Aneesh graduated with a degree in finance in 2011 and hopes to combine his medical and business knowledge as a hospital administrator in the future.

Lindsey Lee

Lindsay is a junior at the University of Tennessee majoring in mathematics and Spanish and minoring in Portuguese.  Her research in PDSR has focused on using natural language processing to look for adverse events in patient records.  At UT Lindsay also tutors mathematics, writes for the university newspaper, and volunteers for a Knoxville organization that supports the homeless.

Jacob Schiftan

Jacob is a sophomore majoring in Biomedical Engineering, with a concentration in biomechanics, at the University of Michigan, Ann Arbor.  Within the PDSR group, he conducted a retrospective evaluation of the usefulness of routine laboratory coagulation testing.  As a Nashville native, Jacob is a dedicated volunteer for Habitat for Humanity.  Jacob is also interested in entrepreneurship, with plans to study for a Masters of Entrepreneurship.

Paul W. Hannam

Paul is a rising second year medical student at Meharry Medical College and is very interested in the practice of Family Medicine.  He is married with two children who are awesome.  He comes from a large family in Jamaica and knows the sense and importance of community.  It is his belief that family medicine is the future to reducing the sky rocketing health care cost in the United States, as family and preventative medicine are vital to long term health of the population.  He took this summer research to learn more about studying populations of patients and working with the statistics used to evaluate and interpret data.  

Mary Marschner

Mary is a first year medical student at University of South Alabama College of Medicine.  Her project with the PDSR group is focused on analyzing the clinical factors and additional costs associated with late extubation in spine surgeries.  She has a degree in Biomedical Engineering from Vanderbilt University and experience working in healthcare consulting.  Mary is interested in utilizing clinical and financial data to investigate healthcare decisions.

Amlan Bhattacharjee

Amlan is a second year medical student at SUNY Downstate Medical Center in Brooklyn, New York.  His projects at Vanderbilt have dealt with non-routine events during pediatric cardiac surgery and finding demographic predictors for violations of NPO (nothing by mouth) orders.  Amlan studied psychology, chemistry, and statistics at Swarthmore College and developed an interest in decision-making and data analysis in medicine.

Shane Selig

Shane is a sophomore in the School of Engineering at Vanderbilt University, majoring in Computer Science, and hopes to pursue a career in medicine.  He is from Chicago, and has worked on various studies at the University of Chicago.  He is interested in medical informatics with the hope of merging engineering, science, technology, and medicine to enhance the everyday practice of medicine.  He is proficient in Linux, website design, development and programming, HTML, PHP, SQL, Java, Javascript and MatLab.  This summer, he has worked on various research and programming projects with the PDSR group and Perioperative Informatics.  In his free time, he enjoys sailing, running, skiing and photography.
