Kevin Tran

PhD (2016-), <ktran(at)andrew.cmu.edu>

I create and use automated, active machine learning workflows to perform density functional theory (DFT) simulations. I then use these DFT simulations to screen for new catalysts for various applications, such as carbon dioxide reduction or hydrogen evolution. My goal is to discover catalysts that are active, efficient, selective, stable, and cheap so that we can ultimately enable large-scale production of solar fuels. More importantly, I enjoy being with family, playing with my baby nieces, cooking/eating, shooting pool, playing ultimate frisbee, doing yoga, rock climbing, and playing racquetball.

Aini (Pari) Palizhati

PhD (2017-), <apalizha(at)andrew.cmu.edu>

I completed my B.S. in Chemical Engineering at North Carolina State University (Go Pack!). When I was an undergraduate there, I was heavily involved in AIChE and conducted research in Dr. Chase Beisel’s lab for two years. In addition, I was also given opportunities to spend all my summers in the industry. All of these experiences provided me with the privilege to learn from many incredible mentors and inspired me to get into graduate school. CMU was the perfect next step for me (fun fact! My undergraduate academic advisor Dr. Lisa Bullard also graduated from here). Outside of school and research, I am part of the CMU Ballroom Dance Competition Team! It has become a great way for me to de-stress, learn something new, and meet some of the most interesting and unique people outside of my daily routine.

Junwoong (Jun) Yoon

PhD (2017-), <junwoony(at)andrew.cmu.edu>

My research focuses on deep learning and its applications in catalyst screening. I apply recent architectures of state-of-the-art Convolutional Neural Network (CNN) to predict catalyst properties. My goal is to design CNN architectures that can find better representations of atomic structures of materials to yield predictions with DFT-level accuracy. It will enable me to accelerate the catalyst screening process while minimizing the number of DFT calculations conducted. Further, it will also allow for the use of Deep Reinforcement Learning (DRL) for identifying metastable catalysts by providing accurate interatomic potentials for a given atomic configuration. In parallel, I always keep an eye out for (and sometimes buy) stocks for long-term investment. I am also interested in studying stock trading algorithms and strategies using machine learning.

Muhammed Shuaibi

PhD (2018-), <mshuaibi(at)andrew.cmu.edu>

My research focuses on graph neural networks and deep learning approaches to catalysis. I strive to develop models and frameworks capable of accelerating atomistic simulations by orders of magnitude while retaining ab-initio level accuracy. I work closely with collaborators at Facebook AI Research (FAIR) to build datasets and models to meet such goals. Additionally, I explore active learning techniques to tackle similar problems in the small-data regime. Outside of work I enjoy spending time with family and friends. I am extremely competitive when it comes to sports and board games – my favorites being volleyball and Catan. My wife and I love exploring cities, parks, and new food places.

Nicholas Tiwari

PhD (2019-), <ntiwari(at)andrew.cmu.edu>

I obtained my B.S. in Chemical Engineering from Rowan University in Southern New Jersey. I conducted research in the Mixing Group under the direction of Dr. Robert Hesketh, Dr. Arthur Etchells and Dr. John Thomas. Here, I used Computational Fluid Dynamics software (CFD) to simulate stirred-tank systems for industrial application. During my time at Rowan, I was afforded a variety of experiences and connections, both industrial and academic. Each experience helped to shape my own thoughts on my future and research, culminating in my decision to attend Carnegie Mellon University. Through my research, I hope to convey the wide-reaching impact of chemical engineering. Outside of my research, I enjoy almost any physical activity. I run, lift weights, square dance, and play a variety of sports including intramural frisbee, volleyball and flag football.

Kirby Broderick

PhD (2019-), <kbroderi(at)andrew.cmu.edu>

I graduated from Georgia Institute of Technology in May 2019 with a B.S. in Chemical and Biomolecular Engineering.

Undergraduate research afforded me the opportunity to work on fascinating problems alongside a lot of interesting people, leading me to join the Ulissi Group in late 2019. Here, I plan to develop new catalysts for hydrogen evolution and get better at tackling complex problems. Outside of research, I enjoy cooking, reading, and staying active.

Unnatti Sharma

PhD (2019-), <usharma(at)andrew.cmu.edu>

I completed my bachelor’s degree in Chemical Engineering from Indian Institute of Technology - Hyderabad (IITH). There I worked with Dr. Praveen Meduri on photocatalytic hydrogen evolution. My aim here was to find or create a material that could photocatalytically split water to generate hydrogenthat could be used as fuel. I also worked with Dr. Phanindra Jampana on Compressed Sensing and System Identification in order to better understand what went into the working of large-scale chemical processes. During my time as an undergraduate student I enjoyed being part of various cultural activities and taking up positions of responsibility in the student council. Here at CMU, as an international student, I discover wonderful new things every day; like cornbread and Halloween, and an amazing work environment. I enjoy reading fiction and fantasy novels, cooking and dancing. I love anime and dogs! My favourite way to procrastinate is playing cards or board games with my siblings.

Matt Adams

PhD (2019-), <madams2(at)andrew.cmu.edu>

I completed my bachelor’s degree in Chemical Engineering at the University of Tennessee, Knoxville. During my time as an undergrad there, I performed research which involved running both experimental reactions and density functional theory (DFT) simulations on intermetallic compounds to evaluate their performance in enabling CO2 reformation. As manually performing DFT simulations is far too slow for effective catalyst discovery, I became interested in learning and utilizing machine learning methods to accelerate the discovery process. My goal is to utilize my skills to discover new materials in order to create a more sustainable energy economy. In my free time, I enjoy cooking, biking, photography, and playing video games.
