Lea Steffes
Instructor, Pediatrics - Pulmonary Medicine
BioDr. Steffes, a Wisconsin native, completed medical school and pediatric residency at the Medical College of Wisconsin. She then moved to the Bay Area and completed her clinical fellowship in pediatric pulmonary medicine at Stanford University in 2020. Additionally, Dr. Steffes received further post-doctoral training in the laboratories of Dr. Maya Kumar and Dr. David Cornfield, studying the cellular and molecular mechanism driving pulmonary vascular disease. In addition to her role as an Instructor in Pediatrics in the division of Pulmonary Medicine, Dr. Steffes is also completing an advanced clinical fellowship in Pulmonary Hypertension at Lucile Packard Children’s Hospital Stanford. Her clinical work consists of caring for patients with pediatric pulmonary and pulmonary vascular diseases such as pulmonary hypertension, bronchopulmonary dysplasia, interstitial lung disease, respiratory failure, chronic cough and asthma. Her research is focused on the vascular changes seen in pulmonary hypertension, more specifically understanding the cellular characteristics of occlusive neointimal lesions, the abnormal cells that block pulmonary blood flow in pulmonary hypertension. In her most recent work, Dr. Steffes identified a subset of healthy vascular smooth muscle cells that are the cell of origin for the pathologic neointimal cells and a specific signaling pathway, that when blocked, inhibits the formation of neointimal lesions.
Dr. Steffes is currently employing advanced single cell sequencing technologies to further understand neointimal cells with the ultimate goal identifying new therapies for pulmonary hypertension, a fatal disease with no known cure. -

Meghan Sumner
Associate Professor of Linguistics
BioI am an Associate Professor of Phonetics at Stanford. My work simplified: I take sound patterns that exist in languages and associated variation and usage patterns (who says what, how and when), and investigate the social meaning humans associate with these patterns (and how they come to make these associations). I care about how, cognitively, this social information affects attention, perception, recognition, memory, and comprehension. Then, I take all of that, and investigate the areas in which language and society interact and highlight how this advances theory, but also how stereotype and bias are reinforced through spoken language. Much of what we currently know about speech variation, language and cognition stems from experiments that probe one component of this process at time, leave out social factors and experience, use stimuli from normative white talkers, and are quite distant from the interdisciplinary and diverse research needed to advance theories and address issues relevant to society. My general focus is on understanding the mechanisms and representations that underlie spoken language understanding and how they interact across various listener and speaker populations in a social and dynamic world.

James Swartz
James H. Clark Professor in the School of Engineering and Professor of Chemical Engineering and of Bioengineering
Current Research and Scholarly InterestsProgram Overview
The world we enjoy, including the oxygen we breathe, has been beneficially created by biological systems. Consequently, we believe that innovative biotechnologies can also serve to help correct a natural world that non-natural technologies have pushed out of balance. We must work together to provide a sustainable world system capable of equitably improving the lives of over 10 billion people.
Toward that objective, our program focuses on human health as well as planet health. To address particularly difficult challenges, we seek to synergistically combine: 1) the design and evolution of complex protein-based nanoparticles and enzymatic systems with 2) innovative, uniquely capable cell-free production technologies.
To advance human health we focus on: a) achieving the 120 year-old dream of producing “magic bullets”; smart nanoparticles that deliver therapeutics or genetic therapies only to specific cells in our bodies; b) precisely designing and efficiently producing vaccines that mimic viruses to stimulate safe and protective immune responses; and c) providing a rapid point-of-care liquid biopsy that will count and harvest circulating tumor cells.
To address planet health we are pursuing biotechnologies to: a) inexpensively use atmospheric CO2 to produce commodity biochemicals as the basis for a new carbon negative chemical industry, and b) mitigate the intermittency challenges of photovoltaic and wind produced electricity by producing hydrogen either from biomass sugars or directly from sunlight.
More than 25 years ago, Professor Swartz began his pioneering work to develop cell-free biotechnologies. The new ability to precisely focus biological systems toward efficiently addressing new, “non-natural” objectives has proven tremendously useful as we seek to address the crucial and very difficult challenges listed above. Another critical feature of the program is the courage (or naivete) to approach important objectives that require the development and integration of several necessary-but- not-sufficient technology advances. -
