David E. Oji
Clinical Assistant Professor, Orthopaedic Surgery
BioDr. David Oji is a board certified and fellowship trained orthopaedic surgeon specializing in the operative and non-operative treatment of all aspects of foot and ankle disorders. After finishing his orthopaedic surgery residency at The Johns Hopkins Hospital, he did his fellowship at Union Memorial Hospital in Baltimore, Maryland under the leadership of Dr. Lew Schon, the former president of the American Orthopaedic Foot and Ankle Society. There he underwent advanced training in the forefront of foot and ankle surgery including total ankle replacements, use of stem cells to promote healing of acute and chronic conditions, non-fusion techniques of great toe arthritis, and complex ankle and foot reconstruction.
During his training, he assisted in treating the Baltimore Orioles and amateur ballet dancers. Dr. Oji also took part in conducting advanced biomechanical and clinical research and has written chapters in textbooks with topics ranging from arthroscopic treatment of talar cartilage defects to the diabetic foot.
After fellowship, he was in private practice working closely with the community as the team physicians for many of the local high school sports teams.
In June of 2017, Dr. Oji joined the Department of Orthopaedic Surgery at Stanford University School of Medicine as a Clinical Assistant Professor. In addition to his usual clinical and educational responsibilities, he is also one of the team physicians for Stanford University Athletic programs.
Since starting at Stanford, he has been on the forefront of ankle and foot surgery. He has performed the first out patient total ankle replacement and the first total talar replacement at Stanford. He is an advocate of minimally invasive ankle and foot surgery performing one of the first MIS (minimally invasive surgery) bunion surgeries in the Bay Area. Whenever possible, the smallest incision and the least invasive approach will be done to allow the patient to heal faster including tendosopy, small joint arthroscopy, endoscopic Haglund's resection, minimally invasive osteotomy, and minimally invasive great toe cheilectomy.
He has a special focus in the treatment of ankle and foot orthopaedic sports injuries such as chronic ankle instability, cartilage injuries, Achilles injuries, using surgery only as a last resort to return the patient to peak athletic form.

Derick Okwan
Assistant Professor of Pathology
Current Research and Scholarly InterestsBroadly, the Okwan lab’s primary interest is to understand how and why the immune system contributes to nearly all chronic diseases. The immune system of the modern human has evolved from a history of stress to the species: famines, continual bouts of lethal pandemics, as well as major climate/environmental and migratory changes that exposed the immune system to novel threats. At the forefront of these challenges are innate immune cells, particularly neutrophils, the most abundant leukocytes. For the first time in human history – at least in the western world- we live in an era of abundance. The Okwan lab is interested in understanding how this traumatic history creates a functional mismatch for the neutrophil, which we believe underpins their roles in chronic diseases of the modern era: cancer, cardiovascular disease, neurodegeneration, and autoimmune disorders. Rather than wholesale depletion of neutrophils and innate immune cells, we seek to identify novel approaches to leverage these cells to combat various diseases.

Kathryn Meyer Olivarius
Associate Professor of History
Current Research and Scholarly InterestsI am an historian of nineteenth-century America, interested primarily in the antebellum South, Greater Caribbean, slavery, and disease. My research seeks to understand how epidemic yellow fever disrupted Deep Southern society. Nearly every summer, this mosquito-borne virus killed up to ten percent of the urban population. But it also generated culture and social norms in its fatal wake. Beyond the rigid structures of race and unfreedom in Deep Southern society, I argue there was alternate, if invisible, hierarchy at work, with “acclimated” (immune) people at the top and a great mass of “unacclimated” (non-immune) people awaiting their brush with yellow fever languishing in social and professional purgatory. About half of all people died in the acclimating process.
In New Orleans, alleged-imperviousness or vulnerability to epidemic disease evolved into an explanatory tool for success or failure in commodity capitalism, and a justification for a race- and ethnicity-based social hierarchy where certain people were decidedly less equal than others. Disease justified highly asymmetrical social and labor relations, produced politicians apathetic about the welfare of their poor or recently-immigrated constituents, and accentuated the population’s xenophobic, racist, pro-slavery, and individualist proclivities. Alongside skin color, acclimation-status, I argue, played a major role in determining a person’s position, success, and sense of belonging in antebellum New Orleans.
Most of all, disease provided the tacit justification for who did what work during cotton and sugar production, becoming the essence of an increasingly elaborate and tortuous justification for widespread and permanent black slavery. In the Deep Southern view, only enslaved black people could survive work like cane cutting, swamp clearing, and cotton picking. In fact, proslavery theorists argued, black slavery was positively natural, even humanitarian, for it protected the health of whites—and thus the nation writ large—insulating them from diseased-labor and spaces that would kill them.
By fusing health with capitalism in my forthcoming book Necropolis, I will present a new model—beyond the toxic fusion of white supremacy with the flows of global capitalism—for how power operated in Atlantic society.
I am also interested in historical notions of consent (sexual or otherwise); slave revolts in the United States and the Caribbean; anti- and pro-slavery thought; class and ethnicity in antebellum America; the history of life insurance and environmental risk; comparative slave systems; technology and slavery; the Haitian Revolution; and boosterism in the American West. -

Anthony Oro, MD, PhD
Eugene and Gloria Bauer Professor
Current Research and Scholarly InterestsOur lab uses the skin to answer questions about epithelial stem cell biology, differentiation and carcinogenesis using genomics, genetics, and cell biological techniques. We have studied how hedgehog signaling regulates regeneration and skin cancer, and how tumors evolve to develop resistance. We study the mechanisms of early human skin development using human embryonic stem cells. These fundamentals studies provide a greater understanding of epithelial biology and novel disease therapeutics.

Franklin M. ("Lynn") Orr, Jr.
Keleen and Carlton Beal Professor in Petroleum Engineering, Emeritus
Current Research and Scholarly InterestsResearch
My students and I work to understand the physical mechanisms that control flow of multiphase, multicomponent fluids in the subsurface, using a combination of experiments and theory. The theory part includes numerical simulation of flow in heterogeneous porous rocks and coalbeds, often using streamline approaches, and it also involves solving by analytical methods the differential equations that describe the interactions of complex phase equilibrium and flow (porous rocks containing more than one flowing phase can sometimes act like a chromatograph, separating components as they flow). The experiments are used to test how well the models describe reality. Applications of this work range from enhanced oil and gas recovery to geologic storage of carbon dioxide (to reduce greenhouse gas emissions) to the transport of contaminants in aquifers.
Teaching
I teach a courses for graduate students on the mathematics of multiphase, multicomponent flow in porous media and on the thermodynamics of phase behavior. I also teach an undergraduate course on energy for freshmen.
