Christopher Michael Reddy (born 1969) is a senior scientist in the Department of Marine Chemistry & Geochemistry of the Woods Hole Oceanographic Institution (WHOI) and faculty member of the MIT-WHOI Joint Program in Oceanography/Applied Ocean Science and Engineering. He is a scientist, an educator, and an inventor. 

Reddy's research includes the source, fate, and transport of combustion-derived materials, PCBs, and DDT; the environmental chemistry of oil spills, biofuels, plastics, and nanoparticles; and the development of environmentally friendly products. He is considered a leading scientist on oil spills and conducted an in-depth and long-term investigation into the Deepwater Horizon oil spill and its long-term aftereffects. 

Reddy is a prolific and highly cited author and holds eleven U.S. patents. He has testified before the U.S. Congress five times, written more than 20 opinion pieces, and given hundreds of interviews for print, radio, and television. Using clips from the original Star Trek television series, he gave a TEDx talk on the role of science in a crisis. A newly discovered microbe that can aid in the breakdown of hydrocarbons was named in his honor.

Early life and education

Reddy grew up on Rhode Island’s Narragansett Bay and has always lived within a few miles of the coast. After attending public schools in Rhode Island, Reddy earned a BS in chemistry with a minor in mathematics from Rhode Island College, graduating in 1992. While there, he was named the American Chemical Society's Outstanding Undergraduate Student in 1991. In 1997, he was awarded a PhD in chemical oceanography from the Graduate School of Oceanography at the University of Rhode Island. While a graduate student, he was named the American Chemical Society's Outstanding Graduate Student in Environmental Chemistry.

Reddy also has an executive education certificate in management and leadership from MIT's Sloan School of Business (2010) and leadership training from Harvard University's Kennedy School of Government (2008).

Career highlights

After receiving his BS in 1992, Reddy worked as a chemist for ULTRA Scientific in North Kingstown, RI, and then as an environmental chemist for CEIMIC Corporation located in Narragansett, RI, from 1993 through 1994. While earning his PhD at URI, he worked as a research graduate assistant in chemical oceanography.

Reddy began his employment with Woods Hole Oceanographic Institution's Department of Marine Chemistry and Geochemistry in 1997 after earning his PhD and has remained there since, as a post-doctoral scholar and investigator (1997–2000), assistant scientist (2000–2004), associate scientist (2004–2006), associate scientist with tenure (2006–2010), and senior scientist (2010–present). Also at WHOI, he was manager of the WHOI Small Boats Fleet from 2008–2014 and director of the Coastal Ocean Institute from 2008–2015. 

During his time with WHOI, Reddy was also a visiting scholar at Scripps Institution of Oceanography at UC San Diego, La Jolla, CA, in 2003 and a visiting associate at the California Institute of Technology's Division of Geologic and Planetary Sciences located in Pasadena, CA, in 2005.

Research areas

Oil spills

According to geologist and biogeoscientist Timothy Eglinton, Reddy is “one of the most innovative, dynamic and prominent environmental organic geochemists” and has made “key contributions to topics of major and pressing environmental concern.” His work on oil spills has had far-ranging and paradigm-shifting impacts on responding to spills, monitoring the recovery (or lack thereof) of impacted areas, assessing damage, and identifying the type and source of spilled oil. He is best known for his and his team’s work on determining “the processes that regulate the fate of petroleum following release to the environment” and for the invention of the application of comprehensive two-dimensional gas chromatography (GCxGC) that enables identification of these processes and that he patented. 

As it degrades in a marine environment, oil undergoes complex transformations, producing residues composed of extremely complex organic mixtures that accumulate in protective environments such as those afforded by fiddler crabs and marsh grass. These residues form the majority of the unresolved complex mixture (UCM) resulting from the breakdown of crude oils which GC had previously been unable to resolve but which Reddy’s novel GCxGC application has made accessible, enabling determination of “the underlying processes controlling petroleum fate” as it degrades in a marine environment. For this invention, Reddy was awarded the Clair C. Patterson Award in 2014 by the Geochemical Society for "an innovative breakthrough in environmental geochemistry of fundamental significance within the last decade, particularly in service to society. To be viewed as innovative, the work must show a high degree of creativity and/or be a fundamental departure from usual practice while contributing significantly to understanding in environmental geochemistry."

Reddy's investigation into an oil spill that had occurred along West Falmouth Harbor, Massachusetts, in 1969 revealed chemical and biological effects that had persisted even after 30 years in fiddler crabs and salt marsh grass. The results of this study, which lasted from 1999 to 2008, led to significant advances in oil spill remediation. Similarly, Reddy and the WHOI chemistry team conducted an extensive study of the Bouchard Oil Spill, which occurred in Massachusetts’ Buzzards Bay in 2003, using GCxGC.
  
Reddy and his team were some of the first chemists involved in the 2010 Deepwater Horizon disaster in the Gulf of Mexico and spent the following ~10 years investigating the Deepwater Horizon oil spill and its aftermath. Reddy was thus involved in mapping the surface plumes, characterizing the oil and gas emitted from the seafloor, estimating the flow rate of oil streaming from the damaged well, modeling the fate of oil and gases in the ocean and atmosphere, monitoring the breakdown of the oil, and gauging the efficacy of dispersants. 

Reddy and his team members were unfortunately drawn into the ensuing legal aspects of the spill when the U.S. Government used the data he and his team had collected to determine how much BP owed by way of restitution. BP challenged the amount of this restitution and requested Reddy's and his team members' emails and personal correspondence for the time period over which they had studied the spill, a request with which they were reluctantly forced to comply in 2011 following litigation. The Deepwater Horizon spill also led to one of Reddy's appearances before the U.S. Congress, testifying on 15 June 2010 regarding government agencies' preparedness to respond to crises such as Deepwater Horizon.

Reddy is currently working with UC Santa Barbara researchers to investigate natural oil seepage from the ocean floor off the coast of California.

To honor Reddy’s contributions to the study of oil spills, a newly discovered marine microbe capable of degrading branched alkanes was named Candidatus Reddybacter in his honor.

Other research

In addition to oil spills, Reddy is engaged in research  related to degradation of other chemicals and plastics that have been dumped or spilled in the ocean (e.g., the 2021 nurdle spill off the coast of Sri Lanka), development of biofuels, replacement of hydrocarbons from fossil fuels in personal care products with chemicals derived from marine algae, and design of safer and more sustainable plastics.

Science communication

While not typically considered an area of scientific research, Reddy apparently views communication of scientific matters to diverse audiences and "building connections between the scientific community and societal stakeholders" to be an important part of being a scientist and has sought to develop and communicate this skill to peers and students. As a consequence, Reddy received the 2023 James T. Grady-James H. Stack Award for Interpreting Chemistry for the Public and the 2018 GSU Ambassador Award for "embod[ying] the concept of a scientific ambassador through his tireless efforts to represent, promote, and translate science to a diverse range of groups outside the ivory tower." Reddy is "renowned as a trusted source among journalists, policymakers and government agencies" and has testified before the U.S. Congress five times, once regarding government agencies' readiness to respond to such environmental disasters as the Deepwater Horizon oil spill. A colleague, David L. Valentine, distinguished professor of geochemistry and microbiology at the University of California, Santa Barbara, stated, “Chris excels in elucidating the ‘how,’ ‘what,’ ‘why’ and ‘what’s next?’ in engaging, clear and bias-free ways."  Reddy's efforts extend to influencing the next generation of scientists, and he collaborates on a science communication graduate course taught at WHOI titled "How Not to Write for Peer-Reviewed Journals: Talking to Everyone Else." 

Effective communication of scientific information to nonscientists is even more important during a crisis such as the Deepwater Horizon oil spill, Reddy believes, and has been the subject of talks (e.g., his TEDx talk using clips from the original Star Trek television series) and his book, Science Communication in a Crisis: An Insider's Guide.  The latter, which is intended "to help scientists understand how best to communicate their knowledge and expertise in the event of an environmental crisis," draws on Reddy's years of responding to environmental crises and communicating actionable information to peers, journalists, regulators, and the public. John E. Riutta, author of The Well-Read Naturalist, describes the book as "a collection of analyses and recommendations for those ... faced with presenting important scientific information to audiences both large and small during times of profound uncertainty" and terms it "very timely" given "the many destructive environmental and medical crises" that have occurred over recent decades.

Publications
A prolific author, Reddy currently has almost 500 publications in academic journals to his name. As shown by his current h-index of 77 and i-10 index of 215, his publications are highly cited. Reddy's current ResearchGate interest score (10,257) consists of 82% citations and is higher than those of 99% of ResearchGate members.

Reddy has authored two books: Science Communication in a Crisis: An Insider's Guide and one of the A Kids Book About children's series titled A Kids Book About Being a Scientist.

In addition to academic journals, Reddy has been quoted over 100 times in such popular media as newspapers (e.g., New York Times, The Boston Globe), magazines (e.g., Consumer Reports), and news channels (e.g., WWMT).
