Our Story

Tortuga Logic was founded by pioneers in the hardware security space, comprising of 4 Ph.D. level scientists who combined hold over 400 publications. The technology of the company was born out of decades of research done in the labs of Prof. Timothy Sherwood (Computer Science Department, University of California, Santa Barbara) and Prof. Ryan Kastner (Department of Computer Science and Engineering, University of California, San Diego) through millions of dollars in industrial and federal grants. The core technology was the subject of the Ph.D. thesis of CEO Dr. Jason Oberg, who was a graduate student in Prof. Kastner’s research group. Dr. Jonathan Valamehr also focused on hardware security while he obtained his Ph.D. in Prof. Sherwood’s lab.

Dr. Valamehr received his Ph.D. (2013), M.S. (2009), and B.S. (2007) in Electrical and Computer Engineering, all from UC Santa Barbara.

Ryan Kastner, Ph.D.

Dr. Kastner has over 10 years of experience in realm of hardware security. He has served as a principal investigator on various government and industrial grants related to hardware security (over $3 million in toto). This includes the National Science Foundation Innovation Corps award which focuses on commercializing technology from academia. Dr. Kastner is a professor in the Computer Science and Engineering Department at UCSD. His research focuses on computer system design with a focus on critical and real-time applications. He received a PhD in Computer Science at UCLA, a masters degree (MS) in engineering and bachelor degrees (BS) in both Electrical Engineering and Computer Engineering, all from Northwestern University.

Tim Sherwood, Ph.D.

Dr. Sherwood has worked both in industry and academia on hardware security for over a decade. He is a Professor in the department of Computer Science at UC Santa Barbara, specializing in the development of novel computer architectures for security, monitoring, and control. He leads an award-winning research lab focused on these areas, with funding from several major government grants. His work and teaching have both been recognized, as he is the recipient of the 2009 Northrop Grumman Teaching Excellence Award, the National Science Foundation Career Award, and the ACM SIGARCH Maurice Wilkes Award. Prior to joining UCSB in 2003, he graduated with a B.S. in Computer Science and Engineering from UC Davis (1998), and received his M.S. and Ph.D. from UC San Diego (2003).
