He has played a key role in raising national awareness for training and research in bioinformatics. Current research includes developing novel strategies for identifying protein interaction networks, intracellular localization of proteins and identification of functional networks in cells. In systems medicine, he collaborates with biomedical scientists to deepen understanding of diseases associated with insulin resistance. He has served on advisory boards for several biotech and bioinformatics companies, universities, international governmental organizations, and the NIH.
Specializing in inductive theory for understanding nature from observational data. Key terms: equation-free mathematics, chaos, forecasting, detecting causality
Sugihara is a theoretical ecologist who has performed foundational work in the data analysis of complex systems from fisheries to medicine to finance. He gained renown for developing, with Lord Robert May, methods for forecasting chaotic systems, providing the first example of chaos in nature with the diatom populations at Scripps Pier. He has worked with the major institutions on questions of systemic risk and on detecting early warning signs of critical transitions, including the Federal Reserve Bank of New York and The Bank of England. He also worked with fisheries to develop a currently enacted market-based incentive plan for reducing wasteful bycatch and to improve forecasting of wild fish stocks. His current interest in neurobiology and genomics includes collaborations with the Salk Institute for Biological Studies to apply EDM to neurobiology and to problems in gene expression in cancer.

Specializing in combinatorics, algorithms, and the mathematical foundations of data science
Tiefenbruck focuses her mathematics background on developing strong foundations in the teaching of Data Science. She is a lecturer who serves as a core educator in the Data Science major and minor undergraduate education program through the Halıcıoğlu Data Science Institute. Her goal is educating students in the theoretical basis of math that will help them build a solid foundation for whatever direction they choose to take in data science, and other technology specializations. “What I like about the field of Data Science is that it’s so customizable, it’s not just: ‘Here’s a formula, plug it in.’ It’s such a broad field, it covers areas from sports to politics,” said Tiefenbruck. Her educational approach is to highlight the creative side of the academic discipline, and present students with lively projects to spark their imagination, like analyzing trends in the TV quiz show game “Jeopardy!” or predicting the genre of a song based on its lyrics.
Tiefenbruck earned her Ph.D. and master’s degrees in mathematics from UC San Diego, specializing in algebraic and enumerative combinatorics, and her bachelor’s from Loyola University in both math and computer science. Among her academic awards include a GAANN Fellowship (federal support for scholars fulfilling a national need), a Goldwater Scholarship and a Best Teacher award from Jacobs School of Engineering.

Specializing in understanding relationships between neural oscillations, cognition, and disease by combining large-scale data-mining and machine-learning techniques with hypothesis-driven experimental research
Voytek works with students in Cognitive Science, Neuroscience and Data Science, and is a leader of both the neuroscience graduate program and the HDSI Undergraduate Fellowship program. His research focuses on automated science, aging, attention, working memory, and brain/cognition/society interactions His goal is to construct an understanding of cognition built on the first principles of neurophysiology: How can neural systems interact to give rise to cognitive phenomena normally equated with “attention” and “working memory,” and what are the behavioral and cognitive limitations and consequences of these biological constraints? He advocates for stronger communications in science, and focuses on what he calls “the human side of data science.”
Specializing in probability theory and stochastic models of complex networks such as in systems biology and in Internet congestion control
Specializing in probability theory and stochastic models of complex networks such as in systems biology and in Internet congestion control
Williams holds the Charles Lee Powell Chair in Mathematics. She is a leader in the field of probability theory, renowned for her work analyzing traffic congestion within stochastic networks, involving real-world systems running at near-maximum capacity such as congested Internet traffic, assembly line glitches, and roadways at rush hour. She has long applied data science and interdisciplinary approach to research, having worked with colleagues in electrical engineering, mechanical engineering, and other fields to tackle a variety of problems related to heavy traffic in systems such as wireless communications networks. She likes to say, “I eat problems for breakfast.”
Specializing in search for dark matter, supersymmetry, electroweak symmetry breaking, experimental particle physics, distributed high-throughput computing
Wuerthwein is the Distributed High-Throughput Computing Lead at San Diego Supercomputer Center and executive director of the Open Science Grid (OSG), a national cyberinfrastructure to advance the sharing of resources, software and knowledge. His research focuses on distributed high-throughput computing with large data volumes. His research in experimental particle physics research includes searching for new phenomena at the high-energy frontier with the CMS detector (Compact Muon Solenoid) at the Large Hadron Collider at CERN in Geneva. He worked on the team that discovered the Higgs Boson, popularly known as the God particle.
Specializing in statistics and biostatistics, causal inference, clinical trials, machine learning methods, random effects models, survival analysis, interdisciplinary work in bioinformatics and epidemiology
Applying her data science and mathematical expertise to the emergence of biomedical Big Data, Xu utilizes machine learning methods to develop predictions, as well as statistical inference for complex data types. Her interdisciplinary work includes investigating such data analysis as competing risks of cancer versus non-cancer mortality, in the presence of high dimensional covariates. Her research also includes focus on causal inference methodology using propensity scores or instrumental variables, for complex data types and for rare events such as in pregnancy safety data.
Xu and clinical colleague Dr. Christina Chamber co-authored a recent report in JAMA (JAMA. 2018;319(5):474-482) (the Journal of the American Medical Association) that won national attention, finding the prevalence of fetal alcohol exposure effects as much as five times greater than previous estimates and deepening the debate over safety of drinking during pregnancy. The study estimated that fetal alcohol syndrome and alcohol-related disorders are at least as common as autism. The disorders can cause cognitive, behavioral and physical problems that hurt children’s development and learning ability.
Xu earned her Ph.D. in mathematics and a master’s in applied mathematics from UC San Diego, and her bachelor’s in math from Nankai University, China.
She was a postgraduate researcher at the University’s Moores Cancer Center and in the Department of Mathematics before becoming an assistant professor at Harvard T.H. Chan School of Public Health in the Department of Biostatistics, and at the Dana-Farber Cancer Institute’s Department of Biostatistical Science. Among her academic honors are being awarded as a Fellow of the American Statistical Association (ASA), and the winner of an ASA David P. Byar Young Investigator Award, and two excellence in teaching awards from Harvard. Contact: (858) 534-6380 firstname.lastname@example.org | Website: http://www.math.ucsd.edu/~rxu/
