2025 ASN Early Career Investigator Awards

Posted on

The ASN Early Career Investigator Award was established in 1984 to recognize outstanding and promising work by investigators who received their doctorates in the three years preceding the application deadline or who are in their final year of graduate school. (Time since PhD degree can be extended by 1 year for each child born or adopted during this period if the applicant has been a primary care giver. Other forms of exceptional caregiving responsibility [e.g., partner, spouse, aged parent, etc]. or extenuating circumstances will be considered on a case-by-case basis.)

We are pleased to announce that this year’s recipients of the ASN Early Career Investigator Awards are Elizabeth Carlen, Anna Dewar, Ashwini Ramesh, and Jessie Williamson!

  • Jessie Williamson is an integrative ornithologist who studies bird adaptation to elevational gradients using ecophysiology and genomics.
  • Ashwini Ramesh is a parasite ecologist studying dynamics of coinfection, and the progression of infection and competition within hosts.
  • Elizabeth Carlen studies the impacts of urbanization, and inequality in human societies, on the evolution and ecology of urban wildlife including birds and mammals.
  • Anna Dewar is an evolutionary geneticist who uses genomics to answer questions about horizontal gene transfer, social evolution, and adaptation in microbes.

We are very much looking forward to their participation in the ASN Early Career Investigator symposium at the upcoming annual meeting in Athens, Georgia (June 21 from 2:30 to 5:30 PM).

We wish to thank the Early Career Awards Committee members for their hard work evaluating the many competitive applications: Drs. Martha Muñoz, Jean-Philippe Gibert, Chris Moore, and Jesse Weber.
