Alejandro Cuevas


I joined CMU as a Ph.D. student in the Fall of 2019. I am currently working with Prof. Nicolas Christin. Broadly, I study reputation and social influence in online platforms. I’ve mostly conducted this work in the context of online anonymous marketplaces. I am curious about measuring and evaluating reputational outcomes across platforms (e.g., are reputation systems working?). I also think about how social media affects retail users’ financial decisions (e.g., investing). In the past I have worked in a variety of topics within security: vulnerability reproduction, deep learning for binary analyses, anonymous communications, moving target defenses, usable security, and computer security from legal and organizational perspectives.

I obtained my Bachelor of Science from The Pennsylvania State University as a Schreyer Scholar and a member of The Presidential Leadership Academy. I completed my honors thesis under the supervision of Prof. Peng Liu and Prof. Dinghao Wu as a member of the Penn State Cyber Security Lab. In 2023, I was an intern at Microsoft Research’s Plural Technology Collaboratory, mentored by Glen Weyl and Madeleine Daepp. In 2017-18, I was a Research Assistant in the DEDIS Lab at EPFL, under the supervision of Prof. Bryan Ford and Prof. Jean-Pierre Hubaux. I also interned at Microsoft’s CDP Team and PwC’s Advisory branch in 2016 and 2015, respectively.

I am also the co-founder of Redoux, a fragrance brand born in NY. We have received the inaugural Glossier Grant in 2021, and 2x Architectural Digest Cleverest Awards.

I am a recipient of the Cylab Presidential Fellowship 2022-2023, and the IEEE S&P Distinguished Paper Award (2018).
