Dr Karl has a M. Sc. in Biological Process Engineering (2007) and a PhD in biophysics (University of Western Australia, 2012). He has done postdocs in vector-borne diseases epidemiology and entomology at Walter and Eliza Hall Institute , James Cook University and PNG Institute of Medical Research. He is currently a Senior Research Officer in the Australian Institute of Tropical Health and Medicine at JCU and laboratory head of the entomology section at the PNG Institute of Medical Research. He has 65 research papers mainly in the field of vector-borne tropical diseases, a 14 year collaborative history with the PNG Institute of Medical Research and more than 5 years of full-time in-country research experience in PNG.

Dr Karl is currently a project leader in the NIH-funded Asia-Pacific Centre of Excellence in Malaria Research in PNG (2017-2023) and a program director in an Australian Department of Foreign Affairs and Trade-funded program to strengthen surveillance and control of malaria and arboviruses in PNG (Strive PNG, 2018-2020). Dr Karl is also leading the Global Fund to Fight Aids, Malaria and Tuberculosis-funded mosquito monitoring activities in PNG (since 2017) as well as various studies funded by the Bill and Melinda Gates Foundation, Australian National Health and Medical Research Council and the Commonwealth Scientific and Industrial Research Organisation.
