'''Daniel L. Hartl''' (born 1943) is the Higgins Professor of Biology in the Department of Organismic and Evolutionary Biology at Harvard University. He is also a principal investigator at the Hartl Laboratory at Harvard University. His research interests are focused on evolutionary genomics, molecular evolution, and population genetics.<ref name=":0">{{Cite web|url=http://hartlgroup.oeb.harvard.edu/people/daniel-hartl|title=Daniel Hartl|website=hartlgroup.oeb.harvard.edu|access-date=2017-01-03}}</ref>

== Early life == Hartl was born in 1943 and spent his childhood in Antigo, Wisconsin. He has three brothers and grew up with foster children living in his home. Hartl's father worked in a cheese factory and his mother worked nights as a sous chef.<ref name=":1">{{cite journal|last1=Tinsley|first1=H. D.|title=Profile of Daniel L. Hartl|journal=Proceedings of the National Academy of Sciences|date=22 May 2007|volume=104|issue=22|pages=9111–9113|doi=10.1073/pnas.0703562104|pmid=17519326|pmc=1896087|bibcode=2007PNAS..104.9111T |doi-access=free}}</ref>

== Education == Hartl was not exposed to the study of genetics in high school, and he was not sure he would go to college. His high school teacher, Robert Meyer, encouraged Hartl to apply for a scholarship, which allowed him to attend University of Wisconsin–Marathon County in Wausau, Wisconsin for two years.<ref name=":3" /> He had just enough money for tuition, and his brothers bought him a car so he could commute the 35 miles to school.<ref name=":1" /> He then transferred to the main campus of the University of Wisconsin–Madison. He remained at the University of Wisconsin, Madison to earn his PhD in genetics.<ref name=":0" /><ref name=":3" /> Hartl studied ''Drosophila'' (a group of fruit flies) and investigated "the mystery of segregation distortion."<ref name=":1" />

In 1968 he began postdoctoral work at the University of California in Berkeley, where he worked with geneticist Spencer Brown.<ref name=":3" />

== Academic career == Beginning in 1969 Hartl had faculty positions at the University of Minnesota College of Liberal Arts, Purdue University, Arts and Sciences at Washington University in St. Louis, and Harvard Faculty of Arts and Sciences.<ref name=":0" /> He has been at Harvard since 1993.<ref name=":3" /> Hartl is the Higgins Professor of Biology in the Department of Organismic and Evolutionary Biology at Harvard University.<ref name=":3" />

== Research == Hartl began his career studying genetics of segregation distortion in ''Drosophila''<ref name=":1" />''.'' He has published work on population genetic theory, tests of selection,<ref>{{Cite journal|last1=Sawyer|first1=S. A.|last2=Hartl|first2=D.
