Ashok Gadgil

Ashok Gadgil (born November 15, 1950, in Mumbai, India) Is the Andrew and Virginia Rudd Family Foundation Distinguished Chair and Professor of Safe Water and Sanitation at the University of California, Berkeley.

He is a Faculty Senior Scientist and has served as director of the Energy and Environmental Technologies Division at Lawrence Berkeley National Laboratory.

Gadgil specializes in heat transfer, fluid dynamics, and technology design for development.

He has substantial experience in technical, economic, and policy research on energy efficiency and its implementation - particularly in developing countries.

Three of his best-known technologies for the developing-world are "UV Waterworks" (a simple, effective, and inexpensive disinfection system for drinking water), the "Berkeley-Darfur Stove" (a low-cost sheet-metal stove that saves fuelwood in internally displaced person's camps in Darfur), and ECAR (ElectroChemical Arsenic Removal) for removing arsenic from water.

Gadgil advocates for immediate and strategic action on the part of the research community to apply current scientific knowledge to address world-wide issues relating to climate change.

Gadgil holds a physics degree from the University of Mumbai, an M.Sc.

in physics from Indian Institute of Technology Kanpur, and an M.Sc.

(1975) and Ph.D. (1979) in physics from the University of California, Berkeley.

After completing his Ph.D. he spent 5 years working for a non-profit in India before returning to Berkeley.

Gadgil Is the Andrew and Virginia Rudd Family Foundation Distinguished Chair and Professor of Safe Water and Sanitation at the University of California, Berkeley.

He also has been distinguished professor of civil and environmental engineering at the University of California, Berkeley.

In early 1990s, he analyzed the potential for large utility-sponsored projects to promote energy efficient electric lighting in poor households in developing countries, then teamed up with others to design and demonstrate such projects.

For UV Waterworks, Gadgil received the Discover Award in 1996 for the most significant environmental invention of the year, as well as the Popular Science Award for "Best of What is New - 1996".

The Darfur Stoves Project seeks to protect Darfuri women by providing them with specially developed stoves which require less firewood, hence decreasing women’s exposure to violence while collecting firewood and their need to trade food rations for fuel.

The stoves were developed with input from the women who would use them, enabling the designers to ensure that they would not tip over and that they would cook at an appropriate heat.

The Darfur Stoves Project is the first initiative of the nonprofit organization, Potential Energy.

In 1998 and again in 2006, Gadgil was invited by the Smithsonian Institution's Lemelson Center for the Study of Invention and Innovation to speak at the National Museum of American History about his life and work.

In September 2022, Springer published an Open Access graduate-level textbook Co-Edited by Gadgil, Introduction to Development Engineering: A Framework with Applications from the Field, freely downloadable from the Springer website.

Gadgil led a group of about 20 researchers at LBNL conducting experimental and modeling research in indoor airflow and pollutant transport.

Most of that work was focused on reducing indoor radon concentrations in individual houses, and protecting office-building occupants from the threat of chemical and biological attacks.

These have become commonplace in dozens of developing countries since 2000 onward, saving billions of dollars annually to their economies.

"“Every time there is a wicked problem, we should look for what are the wrong-headed incentives that keep it in place... You need to understand the feedback loops that are often complex and interacting that allow a wicked problem to persist. You need to find a way to cut the Gordian knot."

In recent years, he has worked on ways to inexpensively remove arsenic from groundwater used for drinking, and clean-burning biomass stoves, including design, production, and dissemination of the improved cookstoves for Darfur (Sudan) refugees.

Reducing the amount of fuel needed has helped to protect women from assault, for which they are at risk while foraging for fuel.

Gadgil has authored or co-authored at least 213 papers which are cited at least 3,805 times.

He has taught graduate courses at UC Berkeley since 2006 addressing topics such as “Design for Sustainable Communities,” and “Technology and Sustainability”.

At Lawrence Berkeley National Laboratory (LBNL) Gadgil is a faculty senior scientist, and former director of the Environmental Energy Technologies Division (2009–2015).

Gadgil has served as editor of the journal Annual Review of Environment and Resources since 2009.

From 2012 to 2022, Gadgil was the faculty director of the Development Impact Lab at UC Berkeley.

He was elected a member of the National Academy of Engineering in 2013 for engineering solutions to the problems of potable water and energy in developing countries.

"“I tell my students, if you want to take on a problem, take on a problem of scale where if you are successful, you make a real impact.” Ashok Gadgil"

UV Waterworks uses the UV light emitted by a low-pressure mercury discharge (similar to that in a fluorescent lamp) to disinfect drinking water.

Effective disinfection at affordable cost is the primary and most important feature of UV Waterworks—allowing an entire system (including costs of pumps, filters, tanks, housing-structure, consumables, and employee salaries for operation) to sell drinking water at about 2 cents US for 12 liters even in deep rural areas, where personal incomes are commonly less than $1 US per day.

This business model, developed and implemented by WaterHealth International, makes safe drinking water affordable and accessible to even poor communities in developing countries.

it provided safe drinking water for 26-29 million people in India and Africa.

Gadgil is a co-Founder and served as Board Chair of Potential Energy till 2015.

Potential Energy's mission is to adapt and scale technologies that improve lives in developing countries.

Gadgil and Paul Gertler were the founding editors of the Open Access journal Development Engineering, first published by Elsevier in 2016.
