Juan David Visbal Alcala
Graduate, Stanford Center for Professional Development
BioJuan David is a resilient, hard-working, and enthusiastic leader who is changing the world by solving society's challenges through engineering practices and strategies that optimize, innovate, disrupt, and transform positively.
Juan holds a bachelor's degree in Mechanical Engineering with experience working in cross-functional teams, spanning from engineering, R&D, and other relevant technical functions, to marketing, management, and sourcing to drive profitable results for businesses while exceeding stakeholder expectations.
Analytical thinker and problem-solver driven to further develop industry standards to meet society's next-generation needs in terms of energy demands, agnostic fuel transitions, product reliability, accessibility, and circularity creating long-lasting solutions while safekeeping the environment.
Juan attempts to lead by three main principles that developed as a result of past experiences that turned into learning opportunities:
1. A good leader should not become a figure of authority that disrupts confidence or trust among co-workers. A true leader should bridge communication gaps and become a master at developing meaningful interpersonal relationships in the work environment. Success and productivity are enhanced through effective teamwork that stems from deep bonds of trust driven by communication.
2. A good leader should be a great listener. One should be able to understand and show interest in what each teammate has to share. Sometimes there's no need to look for solutions elsewhere but within the teams. One learns to communicate by listening first.
3. A good leader should be receptive and approachable to anyone willing to come up to them. It's impossible to know whether an initiative, project, or idea has potential if the person to whom it needs to be sold is not prone to receive it. The only crazy idea/question is one that is never asked. -
Elisa Mariel Visher

Susan Vleck
Assistant Director Lab and Bio Safety, Biosafety Officer, EH&S, Environmental Health and Safety (EH&S)
Current Role at StanfordCurrent Role: Assistant Director, Laboratory Chemical and Physical Safety Program, and Manager, Animal Research Occupational Health and Safety Program, Department of Environmental Health and Safety
I have been a part of the Department of Environmental Health and Safety at Stanford University since 2012. My original role was as a Biosafety and Biosecurity Specialist to support the ongoing development and implementation of Stanford's Biosafety and Biosecurity Program and ensure safe practices, understanding, and compliance for work done using infectious agents and recombinant DNA. I was promoted to Senior Biosafety and Biosecurity Specialist in 2017, and became Program Manager for the Animal Research Occupational Health and Safety Program. In 2020, I transitioned to my current role of Assistant Director, Laboratory Chemical and Physical Safety Program.
I lead the ongoing development and implementation of Stanford's Laboratory Chemical and Physical Safety Program, and ensure safe practices, understanding, and compliance for work done in a wide array of research labs. I lead and direct a team of 9 management and professional personnel to oversee a broad spectrum of environmental, health and safety programs of significant scope and complexity, and oversee subordinate managers with large program responsibilities. I define and direct the overall activities of the group, and allocate appropriate staffing and other resources to achieve objectives, including development and direction of related policies.
I also directly oversee the Animal Research Occupational Health & Safety Program, which serves a centralized point of contact for people seeking help relating to animal and EH&S issues. This program helps bring together groups within EH&S, as well as EH&S and other Stanford departments, to address safety and health issues relating to animals. These issues can fall under a wide range of topics, including biosafety, chemical safety, ergonomics, occupational injury & illness, trainings, lab safety, radiation safety, housing requirements, animal allergies, lasers and PPE. This program serves the research community, but also any staff, student or faculty who interacts with or work in proximity to animals on campus.
My overall goal in my role as Assistant Director is to support the Stanford research community in performing innovative and exciting research safely.
