Biography

Raj Acharya is Head, Department of Computer Science and Engineering at Penn State University. He was a Research Scientist at General Electric (Thomson) CSF Laboratory, Paris, France. He has been a Research Fellow at various NASA and DoD labs. He is a Fellow of IEEE and AIMBE.

His main research focus is in the areas of Bioinformatics, Health Informatics, Network Sciences & Engineering, Cyber Enabled Discovery, and Digital Government. The algorithms he has developed are routinely used in industry and academia. His research is sponsored by National Science Foundation, National Institutes of Health, and various industries. His fractal algorithms are used to monitor bone conditions of astronauts under microgravity conditions. He has shown that the DNA replication and transcription sites exhibit a higher order fractal like behavior.

He is Associate Editor of IEEE/ACM Transactions on Computational Biology and Bioinformatics. He is Founding Chair of IAPR Technical Committee on Pattern Recognition in Bioinformatics. He is the General Chair of the 2009 International Conference on Pattern Recognition in Bioinformatics (Sheffield, UK).

Acharya and his work have been profiled in publications such as Businessweek, Mathematics Calendar, Drug Discovery, Diagnostic Imaging, Environnews, EurekAlert, Science Daily, and The Scientist among others. He is working as part of a multidisciplinary international team on a NSF-United Nations Digital Government Surveillance project involving Hot Spot Bio-Geo Informatics.

He has initiated 4 Centers of Excellence at Penn State. He has assembled a university-wide multidisciplinary team to secure a NSF Research infrastructure grant. He has initiated a Graduate Certificate in Embedded Systems (jointly with CMU) and a Graduate Certificate in Security. He is on a University wide team to create an umbrella graduate degree in Homeland Security. Acharya has initiated multi-nation IT Learning Institute (India, China), which imparts global engineering education to students.

He has recruited 15 new tenure-track faculty. 8 of the eligible 10 junior faculty have been awarded NSF Career grants since 2001. Two junior faculty were awarded the prestigious NSF PECASE award in January 2010 by President Obama.

During his tenure, Penn State CS research expenditure has moved from 64th (2001) to 8th (2007) in the nation. US News & World Report ranks the CE Doctoral program 18th in the country. The CSE Department was awarded the $35.5 Million US Army Network Sciences Center this year.
