Personal Brief

Woosuk Lee is an Elec­tri­cal Engi­neer­ing Researcher in the Microsoft Applied Sci­ences Group, where he con­ducts mul­ti­dis­ci­pli­nary research and devel­op­ment for next-gen­er­a­tion com­pu­ta­tion and human-com­put­er inter­ac­tion tech­nolo­gies. Before join­ing the team, he worked at a research insti­tute, stan­dard­iza­tion orga­ni­za­tion and earned a Ph.D. degree in Elec­tri­cal and Com­put­er Engi­neer­ing at Pur­due Uni­ver­si­ty. He is inter­est­ed in the design and imple­men­ta­tion of embed­ded sys­tems hard­ware and soft­ware to address the new chal­lenges in emerg­ing com­pu­ta­tion sys­tems. His works have been pub­lished as sev­er­al journal/conference papers and patents, and some of them received sev­er­al design con­test awards in recog­ni­tion of enabling new par­a­digms of debug­ging and com­mu­ni­ca­tion tech­nolo­gies.
