IDRE Fellow Bios

Robert Fofrich

Robert Fofrich’s research centers on understanding the causes and solutions to anthropogenic global environmental change. He is particularly interested in climate change attribution, helping vulnerable communities from existing and projected environmental changes, and finding ways to mitigate anthropogenic influences on the Earth system. At UCLA, his work analyzes the trade-offs associated with biogenic climate change mitigation pathways. While climate change is one of our generation’s most pressing environmental issues, many climate pathways that successfully avoid 2oC rely upon diverting large areas of land from native ecosystems and agricultural production to climate change remediation. This is of particular concern in the tropical regions, given the potential for biodiversity and carbon storage loss in addition to the disruption of regional food systems. Additionally, due to the biophysical constraints governing plant growth, numerous biogenic climate solutions cannot thrive under specific environmental conditions, particularly in regions where they exist at the edge of their climatological niche. As a result, the viability of the tropics for biogenic energy production is expected to decline under future warming scenarios and thus warrants further investigation.

About Robert Fofrich

Robert Fofrich was born in East Los Angeles and is an alumnus of West Los Angeles College. Currently, he is a UC President’s Postdoctoral Fellow at the Institute of the Environment and Sustainability and works under the supervision of Dr. Elsa Ordway and Dr. Thomas Smith within the Department of Ecology and Evolutionary Biology. Before joining UCLA, Dr. Fofrich joined the Climate Impact lab and was briefly a postdoctoral scholar in the Department of Earth and Planetary Sciences at Rutgers University. Dr. Fofrich received his Ph.D. in 2022 from the Department of Earth System Science at the University of California, Irvine, where his research focused on energy and agricultural systems as they relate to climate change mitigation and adaptation. He has also served as a researcher at NASA-JPL and the Center for Environmental Biology in Orange County, California. His passion for the natural environment and a profound commitment to underserved communities steered his decision to study ways to mitigate anthropogenic environmental damages and protect vulnerable populations from these changes.

Alec Linot

Alec Linot studies the modeling, control, and stability of chaotic dynamical systems. Chaotic dynamical systems are deterministic systems where small perturbations to the system result in dramatically different dynamics over time. Two common examples include weather forecasting and turbulence. Understanding how to model (or predict) these systems is of vital importance, for example, simply knowing when extreme weather events will occur gives people time to prepare for said events. Controlling turbulent flows also presents a major opportunity to reduce the world’s energy consumption by mitigating turbulent drag. It is important that we study the stability of these controlled systems to understand if the control can be maintained.

The major challenge associated with the modeling, control, and stability of these systems is the massive computational cost required for these large-scale systems. As such, his research focuses on reducing this computational cost by creating accurate low-dimensional models, by using fast reinforcement learning tools, and by developing analytical solutions for evaluating stability. 

About Alec Linot

Alec Linot works as a postdoctoral researcher with Professor Kunihiko (Sam) Taira in the Mechanical and Aerospace Engineering Department at UCLA. Prior to working with Prof. Taira, he received a BS in Chemical Engineering from Kansas State University, and a Ph.D in Chemical and Biological Engineering from the University of Wisconsin – Madison.

Namjoon Suh

Namjoon Suh has been focusing on the applications of generative models in tabular data modalities. Specifically, he is working on designing a fake tabular data synthesizer based on a diffusion model. However, it is a challenging task to build such synthesizers as the diffusion model is designed for continuous variables, whereas tabular data often contain heterogenous features. He aims to circumvent this problem by incorporating the idea of auto-encoder, projecting the original tabular data into continuous latent space. Moreover, he is currently working on extending the idea so that the model also works for generating tabular data with temporal dependencies between rows.

Victoria Rolandi

Victoria Rolandi’s research at UCLA focuses on developing and implementing algorithms helpful in characterizing, modeling and controlling turbulent flows, which are of interest to a wide range of engineering applications. Controlling turbulent flows supports reducing human impacts of environmental and noise pollution and is a necessary step for optimization and progress in the design of vehicles. However, turbulent flows are characterized by complex nonlinear dynamics that span a wide range of spatial and temporal scales. This translates into substantial degrees of freedom, making certain analyses unaffordable regarding computational cost and memory allocation. For this reason, the applications of techniques such as resolvent analysis have mostly been restricted to laminar or moderately turbulent flows. In this context, her research aims to combine current concepts in developing computationally tractable techniques and reformulate algorithms for computational speedup and reduction in memory requirement, to extend the applicability of resolvent analysis to highly complex turbulent flows.

About Victoria Rolandi 

Victoria Rolandi obtained a BSc in Mathematics for engineering from Politecnico di Torino and an MSc in Computational science and engineering from Politecnico di Milano. She later completed a Ph.D in Fluid Dynamics at the Institute Supérieure de l’Aéronautique et de l’Espace (ISAE-Supaero) before joining the Mechanical and Aerospace department at UCLA as a postdoctoral researcher at Professor Taira’s Lab. During her MSc, she studied advanced mathematical and numerical methods and specialized in computational fluid dynamics. During her Ph.D, she developed a global stability solver for compressible flows and investigated how compressibility affects the aerodynamic performance and the emergence of instabilities in the airfoil wake for applications in stratospheric flight and Martian exploration by drones. At Professor Taira’s Computational and Data-Driven Fluid Dynamics Group, she works on algorithms for reducing computational costs and memory allocations for analyzing complex high-dimensional fluid flows.

Fangming Xie

Fangming Xie’s research involves developing high-throughput imaging technologies to investigate brain architecture. The mouse brain, with a size about that of a pea, contains more than 100 million cells that are diverse in molecular signature and spatial organization. Despite rapid progress in throughput and resolution, existing methods will take years to measure all the cells in the mouse brain, before any computational analyses to reveal cell types and their spatial organizations. Rather than performing experiments first and analyzing data second, Dr. Xie, together with his mentor Dr. Roy Wollman and labmates, is developing an integrated approach where machine learning is used to design smarter experiments that maximize the information content of spatial transcriptomics experiments. 

Dr. Xie is also a Collaboratory Fellow of the UCLA Institute for Quantitative & Computational Biosciences, where he works in part with neurobiologists including Dr. Larry Zipursky, HHMI to help them analyze and interpret data from the mouse visual cortex.

He then pursued a PhD at UCSD where his research focused on integrative analyses of single-cell transcriptomes and epigenomes of brain cells. Fangming loves neuroscience, genomics, and physics. He believes many parts of these disciplines can be brought together to sharpen our tools and advance our understanding of the brain.

Aviv Solodoch

Dr. Aviv Solodoch’s current research focuses on the overturning circulation, which connects all of earth’s oceans in a global highway of currents. Water which cools and densifies at polar regions sinks to great depths under gravity and gets carried thousands of kilometers between oceans as it slowly rises to the surface again to complete an overturning cycle. The overturning circulation has significant implications for the climate as a whole, since it regulates the rate of exchange of heat and of CO2 between the atmosphere and the deep ocean. Dr. Solodoch investigates processes which impact the pathways and variability of the overturning circulation, using numerical models and analyses of observational data. His present research foci are: (1) Understanding how the overturning pathways depend on the regions in which dense water forms around Antarctica. (2) Developing machine learning methodology to estimate the overturning rate based on available ocean observations.

Casey Youngflesh

Casey Youngflesh’s research takes a cross-disciplinary approach, applying statistical and computational tools to large-scale ecological data. The IDRE postdoctoral fellowship will support research efforts using statistical data integration to quantify how the timing of seasonal ecological events (i.e., phenology) is changing over time, as well as the consequences of these changes. This work is focused specifically on exploring the phenological dynamics in North American migratory birds, a taxonomic group that has declined by nearly 30% over the last 50 years. This work will build upon prior efforts to characterize avian phenological dynamics, using a hierarchical Bayesian approach to integrate a diverse set of data sources within a unified statistical framework. This will take advantage of the wide spatiotemporal breadth of available information, despite considerable heterogeneity and incomplete overlap of these various data resources. This work will have implications for our understanding of how North American birds are responding to environmental change and constraints that may leave some populations more susceptible to the consequences of climate change.

About Dr. Youngflesh

Casey Youngflesh is a quantitative ecologist and postdoc with Morgan Tingley in the Department of Ecology and Evolutionary Biology at UCLA. His research seeks to understand how ecological systems function, how they are responding to rapid global change, and what this might tell us about how best to conserve these systems. He has a particular interest in applying quantitative tools to large-scale data derived from a variety of sources, including citizen science projects, satellite-based sensors, remote camera networks, and field-based efforts. His research efforts have taken him across the world, from Antarctica to the Galápagos Islands, though these days he can mostly be found at his computer trying to make sense of his data.

Ricky Savjani

Ricky Savjani’s research involves finding ways to mitigate motion while patients are undergoing radiotherapy for solid tumors within the thorax and abdomen. Mentors Dan Low, PhD and Anand Santhanam, PhD have pioneered a model-based CT approach in which patients undergo several (25) low-dose, fast helical CT scans while they are breathing freely. At UCLA, we now have scanned over 100 patients with this protocol, allowing us to now build inter-patient frameworks to model the dynamics of respiration. Ricky is developing a generative framework that can drive lung volume deformations using an external surrogate marker – a belt the patient wears that measures abdominal distention. With this framework, Ricky is working towards generating 3D volumetric projections of the anatomical motion during radiotherapy, ultimately allowing for better tumor control and fewer side effects. Ricky is also working closely with industry partner Varian, A Siemens Healthineers Company.
