He is a member of the graduate faculty of the Department of Portuguese and an affiliated faculty member of the Center of Indian Studies and the Department of Women’s and Gender Studies. Walker is also an Affiliated Researcher of the Centro de História de Além-Mar (CHAM) at Universidade Nova de Lisboa, Portugal. From 1994 to 2003, he was a visiting professor at the Universidade Aberta in Lisbon. During Fall term 2010 Walker was a visiting professor at Brown University. In September 2018 he was appointed Guest Investigator at Woods Hole Oceanographic Institution.

Walker serves on the editorial board of the journal Social History of Medicine. He is the recipient of a Fulbright dissertation fellowship to Portugal (1996-1997), a doctoral research fellowship from the Portuguese Camões Institute (1995-1996), and a NEH-funded American Institute for Indian Studies Professional Development Grant for post-doctoral work in India (2000-2002). Walker has also been named a fellow of the Portuguese Orient Foundation (Fundação Oriente), the Luso-American Development Foundation (2003 & 2008), and has held a Wellcome Trust Travel Grant to the Wellcome Trust Centre for the History of Medicine at University College, London (Spring 2003).  Walker also worked as a Lisbon-based researcher (1999-2001) on the Atlantic Slave Trade CD-Rom Database Project (Cambridge U. Press; D. Eltis, S. Behrendt & D. Richardson) and on the Global History of Leprosy Project, Wellcome Unit for the History of Medicine, Oxford University (2003). During the 2003-2004 academic year, Walker taught for the University of Pittsburgh Semester at Sea program.  From 2005 to 2007 he held a U.C. Davis/Mars Research Fellowship while working on the “Colonial Chocolate Project,” coordinated through the University of California Davis Department of Nutrition.  He remains a consultant for the Historical Division of Mars, Inc.  In 2007, Walker was named a senior researcher on a National Science Foundation-funded project to study the competitive sharing of contested religious sites around the globe (2007-2011).  Beginning in December 2010 he held a fellowship from the Gulbenkian Foundation in Lisbon, Portugal, to support the writing of a new monograph on Indo-Portuguese colonial medicine and hybridized medical culture. Walker was named a National Endowment for the Humanities Fellow (July 2012-June 2013).  

Teaching fields include Early Modern Europe, the Atlantic World, the Portuguese and their empire, maritime history and European global colonial expansion. Current research topics include the adoption of colonial indigenous medicines by Europeans; climate data derived from colonial-era archival documentation; slave trading in the Atlantic and Indian Oceans; as well as commercial and cultural links between the Portuguese overseas colonies in Asia, Africa, and the Americas.

Work in Progress:

(Mount Vernon, Virginia:  The Fred W. Smith National Library for the Study of George Washington & University of Virginia Press; publication expected 2019).

3. National Science Foundation Application (initially submitted July 2017). Project Title:  “Assessing Historic Changes in Climate in the Indian Ocean, circa 1500-1950, using American and Portuguese maritime archival sources.”

Collaborators: Timothy Walker (Professor of History; University of Massachusetts Dartmouth), Caroline Ummenhofer (Research Scientist; Woods Hole Oceanographic Institution) and Neil Tangri (Doctoral Candidate in Ocean Environmental Science; Stanford University)

Building on the success of the ACRE and Old Weather projects, we will recover, quantify, and analyze climate records from Portuguese and American whaling archives. With colonial outposts around the Indian Ocean rim and regular shipping traffic between them, the Portuguese observed and recorded regional weather conditions.  Using Portuguese colonial archival sources in India and Portugal, and U.S. whaling logbooks held in New England, climatologists and historians can potentially push global weather data back over 500 years, with a much broader geographical distribution than is currently available. Status: Revise and resubmit in Fall 2018.
