Project Lead, ContaMiNot

Program Manager, Institute for Social Research

Jule Krüger is a Program Manager for Big Data and Data Science in the Institute for Social Research at the University of Michigan. Jule has more than ten years of experience in leveraging social science research and methods to better understand socio-behavioral phenomena in the fields of political violence and human rights advocacy. In recent years, Jule's deep passion for data, measurement and inference has increasingly expanded to environmental issues because she believes that peace, justice and a healthy climate are intrinsically connected. The success of ContaMiNot at Hacks With Friends 2019 to her is a sign that many people are interested in learning how to properly dispose of their waste, and that technology offers an incredible opportunity to help us lower our environmental impact. Jule is super excited to work with the ContaMiNot team to launch this new sustainability app into the wild.

Research Specialist - Senior, Human Genetics

As a ​Chemical Engineer turned ​​Geneticist/Data Scientist, ​A. Bilge Ozel​​ is​ a Research Specialist at the Department of Human Genetics at the University of Michigan Medical School, where​ ​her ​ultimate goal is to devise and apply analytical and computational approaches to discover the genetics behind complex traits and rare diseases​​. She has led and contributed to many ​exciting ​collaborations​ and discoveries over the last 10 years. Her passion with environment and sustainability ​started when she was a teenager during a summer gig at a local newspaper, where she wrote a short op-ed about the piling trash by the river she used to play as a kid. She feels lucky to have met like-minded people along the way, which finally brought her to the amazing ContaMiNot team that worked tirelessly over two days and won Hack with Friends 2019. She is very excited to be a part of such a high impact effort that will help alleviate the contamination problem not only at the University of Michigan but also at many other communities around the world for years to come.
