Assistant Pediatric Residency Program Director
Associate Professor, Pediatrics Infectious Diseases 
Fellowship, Children's Hospital of Philadelphia, Pediatrics Infectious Diseases, 2006
Pediatrics Residency, Children's Hospital of Philadelphia, 2003

Dr. Dawid’s research interests involve understanding the bacterial factors that allow respiratory pathogens to survive and transmit between humans. Her work specifically focuses on the important pediatric pathogen, Streptococcus pneumoniae. This organism is capable of causing a range of infections from ear and sinus infections to pneumonia and meningitis. Although a highly effective vaccine has been in use for several years, the adaptive nature of this organism has allowed it to change its surface properties and escape some of the protection provided by the vaccine. We are interested in determining the mechanism of this adaptation in order to better predict the changes in the bacterial population in response to vaccination.

Pediatric Chief Residents

Katharine Asta

Katharine Asta, M.D., M.S.
Chief Resident, Pediatrics, University of Michigan 2023-2024

I grew up in Virginia and completed my undergraduate degrees at Virginia Tech, where I studied Biochemistry and Nutrition. Following a spark for the intersection of food/sustainable agriculture/health, before medical school I worked on organic farms, served three years in the Peace Corps in Guatemala and Panama, more farms, then worked in clinical research. My husband and I met when we were assigned to the same village as Peace Corps volunteers and intentionally moved to the Ann Arbor area when we returned. We have fallen for Michigan and find new gems to appreciate every year. While I attended medical school here at University of Michigan we lived on a farm, which was challenging and completely rewarding. We love the joy of growing our own food, cooking, and fermenting; I also love baking, knitting, and hiking.

Michigan Difference: Michigan's program checked all the boxes.  Professionally: exposure to clinical volume, supportive atmosphere, faculty that truly care about the wellbeing and success of their learners, and research opportunities (particularly the PPSTP). Personally: Small city with vibrant local businesses and the ability to live on a farm within commuting distance to the hospital.

Laura Getchell

Laura Getchell, M.D.
Chief Resident, Pediatrics, University of Michigan 2023-2024

I have been a New Englander all my life: I was born and raised in southern Maine, attended college at Wesleyan University in Connecticut, where I played softball and majored in Neuroscience, and completed medical school through the Tufts University School of Medicine – Maine Track Program. While I love New England and hope to eventually make my way back there someday, I decided to spread my wings and fly west to Michigan for my Pediatric Residency to experience a new part of the country and because everyone who has ever lived in Ann Arbor has nothing but great things to say about it. In my spare time, I enjoy hanging out with friends, running, hiking, swimming, biking, baking, crossword puzzles, and spending time with all the residency dogs, including my perfect little monster puppy, Frankie!

Michigan Difference: I chose Michigan because of the people and the pride that everyone has for Michigan! The faculty and residents I met on my interview day were friendly, kind, and seemed genuinely interested in me as a person, and the pride they all displayed for the place they work and the patients they serve was contagious.

Emily Masterson

Emily Masterson, M.D.
Chief Resident, Pediatrics, University of Michigan 2023-2024

I spent the first 22 years of my life in sunny Arizona but have always had a special place in my heart for the Mitten State. Growing up, I spent summers visiting my grandparents in Northern Michigan along the Lake Michigan shoreline. I studied biomedical engineering and mathematics at the University of Arizona (Bear Down!) prior to moving to North Carolina for medical school. When I'm not working, you can find me running, hiking, playing volleyball, swimming, biking along the Huron River, riding my Peloton, rock climbing, or walking dogs. I am interested in a career in cardiology and hope to combine my background in medical device design with clinical care.

Michigan Difference: I am continually impressed by the intelligence, humor, and kindness of my co-residents. As a part of the University of Michigan community, Michigan Medicine has incredible access to multidisciplinary collaboration, research, and community engagement. The easy access to both nature and the big city of Detroit make Ann Arbor a great place to live and work!

Resident Assistants

Resident Assistants are a crucial part of every inpatient team and are a hallmark of an innovative, resident-responsive pediatric residency program. They optimize resident learning by taking responsibility for a significant number of administrative tasks that traditionally were assigned to residents including scheduling follow-up appointments, obtaining outside hospital lab results, imaging, and records, coordinating multidisciplinary rounds, and much more.

Beyond all of this, Resident Assistants serve as moral support for our residents and have become an integral part of our residency family. We love them and remain continually thankful for their help and assistance. Please meet the team!

I was on 11W for only a short time when I became really interested in Peds. Cardiology and the amazing work they do, so in 2022 when I was given a change to become a Resident Assistant for their team, it felt like it was meant to be. I pride myself on bringing a positive vibe into the team room every day. I’m here to lighten the residents load in any way I can, even just being a listening ear or the one you can vent to. Fun Fact: I prefer to be called Ketra (pronounced key-tra ). I love listening to audio books, traveling, riding rollercoasters, and spend quality time with my husband and 13 yr. old son.
