Alina Oprea is a Principal Research Scientist at RSA Laboratories, the security division of EMC. Her research interests span multiple areas in computer and communications security including applied cryptography, cloud security, storage security, security in distributed systems, and malware detection. More recently, her research has focused on providing strong assurances to cloud computing users about handling of their data and computation. Alina holds a B.S. degree in Mathematics and Computer Science from University of Bucharest, Romania, and has obtained M.Sc. and Ph.D. degrees in Computer Science from Carnegie Mellon University in 2003 and 2007, respectively. She is the recipient of the 2011 TR35 award for her research in cloud security.
