Justin Oh won a Fulbright Postdoctoral Fellowship for his project “Improving Constructions of Pseudorandom Generators and Efficient Derandomization from Weaker Assumptions” at the University of Haifa, where he will be hosted by Professor Ronen Shaltiel. During his PhD in theoretical computer science at the University of Texas, Austin, Justin studied how to derandomize randomized algorithms in an efficient manner, and how to obtain useful randomness from low quality sources of randomness. This project aims to continue this line of inquiry initiated during his PhD concerning the limits to which randomness can help computation.
