2023 Outstanding Undergraduate Researcher Award Recipients

Congratulations to the recipients of the 2023 Outstanding Undergraduate Researcher Award. This year’s nominees are a very impressive group. A number of them were commended for making significant contributions to more than one research project, several are authors or coauthors on multiple papers, others have created papers for major conferences, as well as producing software, apps and algorithms.

Many of the nominees had been involved in successful summer research or internship programs, many had been teaching assistants, tutors, or mentors, and a number had significant involvement in community volunteer efforts.

CRA gratefully acknowledges the support of Microsoft Research and Mitsubishi Electric Research Labs (MERL), which sponsor the Outstanding Undergraduate Researcher Award program in alternate years. Microsoft Research is the sponsor of this year’s awards.

2023 Selection Committee: Michael Hilton (Carnegie Mellon University), Co-Chair, Monica Anderson (University of Alabama), Co-Chair, Jonathan Bell (Northeastern University), Victoria Interrante (University of Minnesota), Evan Peck (Bucknell University), Raghu Ramanujan (Davidson College), Steve Swanson (University of California, San Diego), Matt Weinberg (Princeton University), Rahmat Beheshti (University of Delaware), and Tony Clark (Pomona College).

Thank you to those who volunteered their time to serve on the selection committee for this award.

A list of the winners, runners-up, finalists, and honorable mentions is below.


SilviaSílvia Casacuberta Puig

Harvard University

Sílvia Casacuberta Puig is a senior at Harvard University, majoring in mathematics and computer science, while concurrently pursuing a Master’s of Science in computer science.  Her research spans a variety of different areas, including matrix algorithms, cryptography, data privacy, algorithmic fairness, machine learning, and computational linguistics.  Her work builds on one of the most mathematically sophisticated approaches to fairness (“outcome indistinguishability”), and her investigation has led to intriguing insights where methods developed for algorithm fairness are shedding new light on classic results in computational complexity such as Impagliazzo’s Hardcore Lemma. In addition to doing great research, Sílvia gives back by being a teaching assistant in a variety of computer science courses.  In addition, she has shown great leadership by serving as co-director of academics of Harvard Women in Computer Science (WiCS), as a co-president for Harvard Gender Inclusivity in Mathematics (GIIM), and starting initiatives such as the WiCS Undergraduate Research Reaching Groups.

CarmenCarmen Strassle

Stanford University

Carmen Strassle is a senior at Stanford University, majoring in physics and mathematics, while also concurrently pursuing a Master’s Degree in computer science.  Her research interests are in the area of theory and algorithms. Her work led to improvements in the lower bounds for decision tree learning, which is a basic algorithmic task. She showed how existing results on the inapproximability for parameterized Set Cover yield qualitative improvements over the state-of-the-art decision tree learning lower bounds, but also how her technique can be combined with recently developed composition lemmas for query complexity to give lower bounds even against the much easier task of testing decision trees. In addition to this work, she has also worked on a second challenge that has shown improvements for the problem of Certification with an NP oracle. In addition to her strong research work, Carmen is a lead tutor for math and physics, as well as a course assistant for computer science and math classes.

ZinengZineng Tang

University of North Carolina at Chapel Hill

Zineng Tang is a senior at the University of North Carolina at Chapel Hill, where he is pursuing his Bachelor of Science degree in computer science and mathematics.  Zineng’s research interests are in the fields of machine learning and natural language processing. His research focuses on two main research questions: how could one perception help the learning of another, and how could different perceptions be learned jointly.  One example of this is VidLanKD, where his work explores how visual data can enhance language learning.  By using a teacher and student framework, the work improves upon previous results, and offers new insights into how language models can learn language beyond text.

ZhihanZhihan Yang

Carleton College

Zhihan Yang is a senior at Carleton College, where he is a double major in mathematics and statistics. His research is in the area of probabilistic machine learning and deep learning. Specifically, his work at Carleton uses multi-armed bandit algorithms to allocate participants to conditions in educational experiments. Using adaptive algorithms in this way offers opportunities to allocate more students to more effective conditions, which is beneficial for students participating in the experiment, but also makes it easier for teachers to conduct experiments in their classes, leading to more effective materials and helping scientists better understand how people learn. Additionally, he has done work on deep generative models for game content generation and deep reinforcement learning for partially observable problems at Northeastern University.


AparnaAparna Gupte

Massachusetts Institute of Technology

Aparna Gupte is a senior at Massachusetts Institute of Technology majoring in computer science and mathematics. Her research interests are in the theoretical aspects of machine learning. Her research fits into two broad themes: the computational complexity of machine learning problems and deep learning theory. She has served as a teaching assistant and tutor at MIT and mentored high school students for a reading program on cryptography.

ZimingZiming Mao

Yale University

Ziming Mao is a senior at Yale University, where he is pursuing degrees in computer science and philosophy. His research interests lie at the intersection of theory and systems, with contributions to natural language processing, data store, caching systems, and memory disaggregation. His research experiences have included multiple layers of the computing stack, from algorithms to applications, to operating systems and hardware. Besides research, Ziming is interested in astrophotography and runs a popular Instagram page, @the.astronomy.daily. He also helps to organize high school outreach events for students interested in computer science.

FranciscoFrancisco Pernice

Stanford University

Francisco Pernice is a senior at Stanford University, where he is pursuing degrees in mathematics and computer science. His research interests are in theoretical computer science, and has worked on projects in algorithmic game theory, error correcting codes for deletion channels. He has served as a teaching assistant for eight quarters and volunteered to help train new students for the role.

fredFengyu Yang

University of Michigan, Ann Arbor

Fengyu (Fred) Yang is a senior at the University of Michigan majoring in computer science with a minor in business. His research interests are centered in computer vision, and he has worked on projects in multimodal perception, semantic segmentation, and crowd analysis. He connects his computer vision research with the real-world by building new datasets that more closely resemble the way that humans interact with the world. He is heavily involved in Model United Nations (MUN) organizations, serving as the president of multiple MUN conferences and leader of MUN classes in high schools.
