Sivakamasundari V
Instructor, Institute for Stem Cell Biology and Regenerative Medicine
BioMy research interests are focused on understanding the molecular basis of early development and stem cells, as it is often aberrations in stem cells or signaling mechanisms between tissues that lead to diseased states, including tumor development and cancer progression. Knowledge of stem cells and development is also critical to develop appropriate cell-based therapies for various diseases or injuries. My prior and current works take advantage of both traditional techniques (gene targeting, lineage tracing) and state-of-the-art technologies (Single cell RNA sequencing, Chromatin Immunoprecipitation (ChIP-seq), Imaging Mass Cytometry) to elucidate fundamental molecular mechanisms underlying signaling in tissue biology.

BioDr. Arturas Vailionis has been an integral part of Stanford University since 2000, serving as the Senior Staff Scientist at Stanford Nano Shared Facilities (SNSF). Within SNSF, he oversees the X-ray Lab, comprising X-ray Diffraction and X-ray Computed Tomography instruments. Additionally, Dr. Vailionis plays a key role as the core lead of the X-ray and Surface Analysis (XSA) group at SNSF. He also holds a Lecturer position in the Materials Science & Engineering Department and serves as a visiting professor at Kaunas University of Technology in Lithuania.
Dr. Vailionis earned his PhD from the Royal Institute of Technology, where he focused on the growth and structural characterization of high-Tc superconductor thin films. Subsequently, he conducted research in the group of Prof. Joe Greene at the University of Illinois at Urbana Champaign, investigating atomic structure, morphology, and growth kinetics of semiconductor and nitride thin films using X-ray Diffraction and Scanning Probe Microscopy.
Dr. Vailionis research interests encompass a wide range of X-ray scattering techniques aimed at understanding structural properties of materials at the atomic level, particularly focusing on complex oxide thin films and heterostructures. He has coauthored over 100 publications covering topics such as microstructure, electronic, and magnetic properties in thin films. Additionally, his expertise extends to tomographic imaging of inorganic and biological materials. -

Sharif Vakili, MD, MBA, MS
Clinical Assistant Professor, Medicine - Primary Care and Population Health
BioSharif Vakili, MD, MBA, MS, (pronouns: he/him), is an internal medicine physician, clinician executive and educator. He practices at Stanford Los Altos Primary Care.
Dr. Vakili has a background in chronic disease management and health systems delivery, believing strongly in a teamwork approach to patient care that empowers patients to navigate the health system as part of their clinical care.
He is active in the research and business communities. His research has been in peer-reviewed journals including NEJM Catalyst, JAMA Network Open and the Annals of Emergency Medicine. He also teaches annually at the Stanford Graduate School of Business.
Dr. Vakili is credited with establishing and coining Remote Patient Intervention (RPI), a model of clinician-supervised AI care delivery first performed at Stanford during a clinical study published in JAMA Network Open. His work has defined the emerging field of Clinical AI, in which artificial intelligence delivers care that would otherwise be performed by a licensed clinician. -

Juan Rafael Valdez
Advanced Lecturer, Language Ctr
BioJuan R. Valdez is a teacher and a writer. He enjoys teaching as a way of helping students to optimally develop their communicative skills, while they also develop a critical sense of community and coexistence in a diverse and complex world. Juan belongs to the tradition of maroon intellectuals and socionaturalists who like to roam between the city and the wilderness and between science and literature. His writings explore the experiences, visions, and stories of those who walk the earth and leave little trace. His publications include: Tracing Dominican identity: the writings of Pedro Henríquez Ureña (Palgrave Macmillan, 2011) and En busca de la identidad: la obra de Pedro Henríquez Ureña (Ediciones Katatay, 2015). His latest book Sendas Extraviadas (Universidad Autónoma Metropolitana-UAM, 2024) is a series of essays on "aimless" walking that explore the possibility of overcoming perilous notions of politics, absurd racism, and consumerist madness. It also proposes strengthening our sense of place and belonging in the world by cultivating our relationship with nature. When Juan is not teaching, studying, or reading, he's hiking, tending to his plants, and having a good laugh.

Carlos Valencia
Undergraduate, Mechanical Engineering
BioBorn in Camarillo, California, Carlos Valencia learned early that challenges forge resilience. As the son of a hard-working immigrant family, he spent summers working in the avocado and lemon industry. Today, as a Mechanical Engineering student at Stanford University, he channels that determination into robotics.
Carlos has worked on numerous projects related to the field. Carlos’s passion for engineering took root in high school. As the former president of the ACHS MESA (Mathematics, Engineering, Science, & Achievement) chapter, he mentored 45+ first-generation students, leading them to compete in national STEM competitions. In the summer of 2024, he worked with L5 Automation, a robotics company based in La Cañada, CA, in Olmos, Peru where he helped develop harvesting platforms for one of the largest agriculture producers in Peru.
Beyond engineering, believes in the power of storytelling to inspire action. His TEDx talk, “Avocados Rot” drew from his upbringing to challenge audiences to seize fleeting chances a message that resonated globally. Recognized as Camarillo Youth of the Year (2023) and awarded the Bronze Volunteer Award by the American Red Cross, he balances innovation with service, whether rebuilding communities after disasters or leading robotics teams.
Carlos’s mission is to democratize STEM access. Carlos envisions a world where education erases barriers. He aims to pioneer low-cost robotic solutions for agriculture and healthcare while expanding mentorship networks for first-gen students. When not engineering or volunteering, he unwinds by hiking, playing soccer, or tinkering with 3D printers.
