Dr. Ergun Akleman is a Professor at the Department of Visualization at Texas A&M University since 2008. He is a professional cartoonist, illustrator and caricaturist who has published more than 500 cartoons, illustrations and caricatures. He is also a computer graphics researcher who has a background in Electronic and Computer Engineering. He received his PhD in Electrical and Computer Engineering from Georgia Institute of Technology. His most significant and influential contributions as a researcher has been in shape modeling and computer aided sculpting. His work on a topological mesh modeling has resulted a powerful manifold mesh modeling system, called TopMod. By using TopMod, high genus manifold shapes can easily be constructed. He also has a significant body of work in subdivision modeling and implicit modeling.

Dr. Tuba Fehr (formerly Tuba Sural) grew up in Istanbul, Turkey and graduated from Bogazici University with dual degrees in Molecular Biology & Genetics, and Chemistry. She obtained her PhD in Genetics at Harvard Medical School, where she studied how chromatin structure regulates gene expression on the X chromosome in fruit flies. During her postdoctoral work at the University of Illinois-Chicago (UIC), she researched cellular mechanisms underlying a rare neurological disease using mouse models. For this work, she was awarded an NRSA individual postdoctoral fellowship from the National Institute of Health (NIH).

Dr. Fehr has also held several leadership positions during her postdoc training, including serving as the President of the University of Chicago Postdoctoral Association, Director of External Relations for the UIC Postdoctoral Association, an elected member of the Board of Directors for the National Postdoctoral Association (NPA), and an appointed steering committee member for the Postdoctorate Leaders section of the Graduate Research, Education and Training (GREAT) group at the American Association for Medical Colleges (AAMC). She has recently transitioned outside the lab into the world of science policy, where she is engaged in federal policymaking as a Science and Technology Policy Fellow at the American Association for the Advancement of Science (AAAS) in Washington, DC.



Dr. Osmanoglu holds a B.Sc. in telecommunications engineering and a Ph.D. in synthetic aperture radar interferometry time-series analysis. His dissertation was selected to be the most original research, and he is the winner of the University of Miami Rosenstiel School F.G. Walton Smith Prize for 2012. His primary area of expertise is radar remote sensing, and he has worked on applications for observing surface deformation, measuring target velocities, boosting signal-to-noise ratio in target detection algorithms, and radar design and instrumentation. Since 2013 he has been working at the NASA Goddard Space Flight Center, on the instrument and algorithm development of P- and L-band digital beam forming synthetic aperture radar systems.
