Short Bio:

In 2011, I graduated an interdisciplinary program of Ben-Gurion University awarding a B.Sc. in Electrical Engineering and a B.Sc. in Computer Science (with honors). In my fourth year project (at AudioCodes), I optimized the performances of a speech vocoder (voice encoder/decoder). Speech vocoders have an inherent Real-Time constraint – the encoding/decoding process must be carried out FASTER than the rate in which the voice signal is sampled and introduced into the system (in other words, the vocoder has to "keep up" with the speaker). Using DSP capabilities, I was able to improve the runtime by (roughly) 90%.

Today, I am a Ph.D. candidate at the Department of Computer Science, Ben-Gurion University. My research is in private data analysis. The task of private data analysis is (in general) to analyze databases containing personal details of individuals, while protecting the privacy of those individuals. For example, a pollster usually promises to protect the privacy of the individuals surveyed. The first course of action that comes to mind is to simply delete all the names and ID numbers from the database. However, such "anonymized" databases are proven time and again to violate privacy; sadly, this "solution" is still being used today.
