Dr. Kamlesh Chauhan, Research Chemist, IIBBL, ARS-USDA
Sustained research productivity: Dr. Kamlesh Chauhan (Kamal) is a highly productive senior
scientist, and an international known expert on vector control and integrated pest management. He
has published 75 peer-reviewed papers (6/year) including 10 issued patents/applications from 20
invention disclosures (2/year 2005-2016). As a Project Director, he leads multi-state teams and has
received 11 grants (exceeding $6 million) from a broad range of funding agencies. During 25 years
of research in the chiral synthesis of biomolecules, Dr. Chauhan has been recognized for his research
on quantitative structure-activity relationships (QSARs) and natural product synthesis. This is
evidenced by over 130 citations of his SAR work on polychlorinated biphenyls in the last ten years.
His three inventions have been adopted by industries under CRADAs and are being sought for
licensing. He has presented 44 invitational lectures in two distinct fields of research including the
plenary lecture at the International Union of Pure and Applied Chemistry’s (IUPAC) Pesticide
Chemistry Symposium (2012). Dr. Chauhan was invited by the Bill and Melinda Gates Foundation to
participate in the “New Initiatives in Vector Control” symposium and more recently by the World
Health Organization to prepare guidelines for developing spatial repellents against biting insect
disease vectors.
Dr. Chauhan's sustained productivity is signified by his receiving 12 outstanding annual performance
awards over the past 15 performance cycles.
Impact on science and technology: Dr. Chauhan is an internationally recognized authority in
pyrethroid and natural product chemistry. His originality is evidenced by his inventions of
commercially viable techniques in the field of natural products chemistry and the development of
structure-activity relationships for toxicants of agriculturally and medically important arthropods.
Dr. Chauhan’s research impact has resulted in outside funding from various agencies/industries
totaling $6.1 million since he joined USDA. Dr. Chauhan was awarded the ARS (2010 and 2014)
and Federal Laboratory Consortium (FLC, 2009 and 2014) Technology Transfer awards, and
Fulbright Specialist Research Fellow status under the International Scholar Exchange program to
share his expertise in vector control. He has synthesized several biologically active molecules not
previously available to researchers, and described their usefulness. His creativity and productivity
has been documented by his three cover page journal articles, 6 issued patents, 4 pending patents, 4
patent applications, seven ARS research magazine articles, and numerous press releases.
Below are some highlights of Dr. Chauhan’s research impact:
Dr. Chauhan's groundbreaking research was used by the insect biocontrol industries. Dr. Chauhan
has demonstrated that simple assumptions that biocontrol agents can be utilized by dispersion of
larvae or adult release of the predators can be averted by utilizing semiochemistry. For example, he
identified and synthesized (ID # 2) the first ever pheromone in the order Neuroptera for the green
lacewings, which is the leading commercially available predatory insect in the world. This research
shifted the trend in use of biocontrol agents in integrated pest management. Dr. Chauhan's research
findings were critical for Department of Defense deciding to prioritize the US registration of
Transfluthrin- a fast acting pyrethroid. Dr. Chauhan invented and patented novel fast-acting
pyrethroids that can overcome resistance against metabolic detoxification by vectors. International
agrochemical companies have funded CRADAs and are seeking licensing for these novel pyrethroids
as reduced-risk public health pesticides (ID # 1,8,13,14). The semiochemistry research Dr.
Chauhan conducted led to impactful inventions. More recently Dr. Chauhan developed attract and
kill baits for mosquito control, a needed tool against impending threats of Zika and dengue viruses.
He also invented practical application of beetle pheromones useful in IPM (ID# 4,7,12,15). Dr.
Chauhan's research findings for dsRNAi delivery. In assisting delivery of dsRNAi-based
biopesticide against the citrus psyllid. Dr, Chauhan discovered (ID # 17,19) chemical ligands to
deliver targeted biopesticides as critical tool for field application.
Discovery of a natural product with antibiotic activity against Citrus greening and food borne
pathogens: This month Dr. Chauhan filed an invention disclosure (ID # 20) reporting a systemic
natural product cure that works against HLB- a gram negative bacteria, threatening citrus industry
across the globe. His contribution fighting antibiotic resistance paved the way for finding natural
products for animal well-being and food produce safety.
Recognized scientific leadership: Dr. Chauhan is devoted to scientific advancement and is a
highly regarded expert in structure activity relationships of natural products. Dr. Chauhan has used
his creativity in applied research along with publishing research articles. His dedication in vector
control and IPM using sustainable chemical tools is noteworthy. Dr. Chauhan’s numerous inventions
in diverse application of natural products are proof of his scientific leadership.
Dr. Chauhan‘s scientific leadership shines in his innovative approaches and his ability to bring
together talents from many scientific disciplines and organizations. Serving as a lead chemist for
the Deployed War Fighter Protection Program, Dr. Chauhan has led a large trans-disciplinary, multistate, and multi-institute research team since the inception of this funded program. He merges life
scientists, engineers, and social scientists, and engages brilliant minds from non-traditional
agricultural fields to research of IPM and insect vector control alike. As a scientific leader and
forward thinker, he constantly seeks new initiatives and novel pathways to accelerate science and
technology advancement. His initiative and preliminary success on natural product antibiotic played
critical role in redirecting in-house project at Environmental Microbiology and Food Safety
Laboratory (EMFSL, 4200-006) in to ‘Identification of Plant-derived Bioactive Compounds for their
Potential as Alternatives to Conventional Antimicrobials’ project. Dr. Chauhan’s contributions
including three inventions in the span of one year for multifaceted approaches against the agents
responsible for citrus greening is a shining example of his scientific leadership in a team
environment.
Development of others. Dr. Chauhan is devoted to training and developing young professionals
and students. Over the course of his 15-year career at USDA Dr. Chauhan has mentored 26
individuals comprising a diverse group of high school students, visiting scientists, post doctoral
fellows and career-seeking new graduates in agricultural scientific research. During the past five
years, through outside funding, Dr. Chauhan hired and trained seven term employees and steered
them to permanent career positions in government, academics and industry. On a regular basis, Dr.
Chauhan used his grant funds in hiring high school interns and college students from land grant
universities. For the last six summers, he hosted minority and female high school interns in his
laboratory; each of whom have gone on to pursue a degree in bioengineering, medicine, dentistry,
and/or agronomy. The recent impact of Dr. Chauhan’s mentoring is evidenced by the full-ride
scholarship of one of the students to Harvard University, the prestigious Meyer-Hoff fellowship to
UMBC and honor scholar award in Georgia Tech to two other students. More recently Dr. Chauhan
is assisting two graduate students (US Navy) from Uniformed Services University of Health Science
in pursuing their degrees in medical entomology and public health sciences. For outreach activities,
Dr. Chauhan has been heavily involved at BARC by giving presentations on research in use of
biocontrol techniques in organic farming and its benefits with Agricultural Research Service (ARS)
to a variety of audiences. Dr. Chauhan was the recipient of the 2014 Beltsville Area Outreach
Diversity and Equal Opportunity (ODEO) award.
