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’m working on darkweb marketplace measurements. In particular, I am curious about how vendors succeed/fail in these marketplaces and whether the reputation systems that exist in these markets work. I sometimes 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 2017, 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).
