Scientific career
Fields

Mark E. Siddall is a Canadian[1] invertebrate zoologist and infectious disease expert.[2]

Siddall's research has focused on the diversity and evolutionary biology of a wide range of parasites, from single-celled microbes to leeches. He has led expeditions throughout the world, most recently including South Sudan, Cambodia, the Lower Amazon of Brazil, and Madagascar. His work ranges from sequencing the whole genome of bed bugs uncovering hemotoxic venom compounds in blood feeding animals, to leveraging iDNA as a measure of endangered animal diversity in protected tropical forests.[3] In addition to over 160 peer reviewed publications,[4] he is author of the whimsical[3] book “Poison: Sinister species with deadly consequences”.[5] Siddall is a committed science communicator making frequent public program appearances, at venues around New York City and more widely; even garnering recognition from the Entertainment Exchange of the National Academy of Sciences.[3] He has curated of the Irma and Paul Milstein Family Hall of Ocean Life and other exhibitions including The Power of Poison, Life at the Limits: Stories of Amazing Species, Picturing Science, Undersea Oasis and Countdown to Zero: Defeating Disease[3] in collaboration with President Jimmy Carter. Siddall received his Ph.D. from the University of Toronto in 1994, is a recipient of the Henry Baldwin Ward Medal from the American Society of Parasitologists and is a Fellow of The Explorers Club.[3]

Education

Siddall completed a Bachelor of Science in Microbiology and Immunology, a Masters [6] and PhD in Parasitology[7] under the supervision of Sherwin S. Desser at the University of Toronto in 1988, 1991 and 1994, respectively.[8]

Career

After completing his PhD in 1994, Siddall started a postdoc at the Virginia Institute of Marine Science under the supervision of Eugene Burreson. Though Burreson is a noted marine leech systematist, their collaborations concerned protozoon parasites of oysters including "dermo" (Perkinsus marinus) and "MSX" (Haplosporidium nelsoni and other economically important species in the parasitic phylum Haplosporidia.[9] That research demonstrated that MSX began wiping out the Atlantic oysters in the Chesapeake Bay and elsewhere as a result of the introduction of oysters from Asia.[10] His phylogenetic work showing that Perkinsus marinus is a dinoflagellate[11][12] overturned environmental monitoring methods.[13] At The College of William and Mary Siddall began working on a solution to the long-standing problem of correlating ordinal fossil age (stratigraphic) data to bifurcating tree structures in a manner that was not biased by the shape of the tree.[14][15]

Subsequently, Siddall was a Michigan Society of Fellow from 1996 - 1999[16] at the University of Michigan where he worked closely with Arnold Kluge taking on Jessica Light (now faculty at TAMU) as an undergraduate intern. It was as a Michigan Society Fellow that Siddall that Siddall drew heavily on Karl Popper in formulating an urgent critique of maximum likelihood for the inference of phylogenies[17]. It was also during this period in which Siddall contributed to understanding the coevolutionary history of HIV coevolution[18][19].

Siddall was hired at the American Museum of Natural History in July, 1999[1] and served there as a curator until September, 2020. The first researcher he sponsored in his new role was Susan Perkins in order to allow her to achieve a major contribution to understanding the evolution of malaria parasites.[20] Siddall took her on as his first postdoctoral scholar, supported her hire at the University of Colorado, and encouraged her to apply to the microbiology curatorship at the American Museum of Natural History.

Siddall took over stewardship of the museum's summer Research Experiences for Undergraduates Program in 2000 shepherding it through two decades of uninterrupted National Science Foundation grant funding. The program saw the mentorship of more than 200 undergraduates in biodiversity and evolutionary biology research, 52% under grant DBI-1358465 were recruited from academic institutions where research opportunities in STEM are limited.[21] Siddall is known for matching the representation of women (71%) and minorities (31%) in the program to the proportions of those applying.[21] Fully 39% of the interns he admitted into the program are in tenure track faculty positions among whom women represent 67%.[21] His former interns include Lauren Esposito at the California Academy of Sciences and Anna J. Phillips at the Smithsonian Institution.

The American Museum of Natural History let him go in September 2020 after the law firm it retained to represent its interests, Kaplan Hecker & Fink[22] led by Roberta Kaplan (co-founder of the Time's Up Legal Defense Fund[23]) provided the museum with a determination that he had sexually harassed a graduate student as conclusion to a complaint that did not include that charge. The choice of Kaplan Hecker & Fink deviated from all prior investigations of sexual harassment at the American Museum of Natural History handled by T&M Protection and which did not result in terminations.[24][25] As part of the investigation, which occurred when the American Museum of Natural History was seeking to fill a $120 million budget gap,[26] Siddall was cited for violating a museum policy that prohibits sexual relationships between staff and mentees under their academic supervision.[27] Siddall denied anything of a sexual nature took place and denied that the graduate student was ever under his supervision.[28] In support of Siddall's claim, the AMNH's own graduate school roster from that time period does not indicate any student being under his academic supervision either in the museum's own Richard Gilder Graduate School Comparative Biology program or in its Collaborative Program at partnering universities.[29]

Worried about data-fabrication in a paper they were coauthoring, Siddall asked to remove his name from the paper on 22 May 2020.[22][28] Within days of that request[28] the graduate student filed a sexual assault complaint that was not upheld in the investigation.[22] Siddall also publicly disagreed with the lesser harassment findings that led to his dismissal, however, he chose to not appeal the decision to protect his family from legal costs as his son was entering remote Kindergarten, his daughter was applying to colleges and his wife was trying to complete her own graduate degree.[22][28] The American Museum of Natural History responded with termination, even though there was no record of a prior sexual harassment complaint against Siddall,[28] thus putting Siddall out of work, and ineligible for unemployment benefits[30] in the middle of a global pandemic.

Communicating Science

Siddall has presented his passion for parasites and biological sciences for a wide range of audiences including TED[31], The Pebble Beach Authors and Ideas Festival[32], Play Fair, Comic Con[33], Idea City[34], the Northeastern Society of Scientific Skeptics, the Humanist Society[35], as well as multiple appearances at the EG Conference[36], The National Academy of Sciences[37][38], The World Science Festival[39][40][41][42], New York's Secret Science Club[43][44] and the Explorers Club[3][45].

He has been invited to participate in in public panel programs with Jimmy Carter and Tom Frieden regarding disease eradication[46], at the Carter Center[47], the Social Good Summit, and the World Economic Forum[48]. He has himself hosted panel programs concerning Big Data[49], and especially disease eradication at the Carter Center[47] and at the World Health Organization[48] while also serving as host and Chair of Public Programs at the Explorers Club[50].

Research

Siddall procured millions of dollars in grant funding for the American Museum of Natural History from the National Science Foundation, the National Institutes of Health, and several private foundations.[51] He has an h-index of 50 having authored 169 peer-reviewed publications that have been cited over 9,000 times.[4] Siddall's expertise covers the biodiversity, detection and disease roles of pathogens and how they inform socioeconomic and ecosystem health.[4] His international field work has covered more than 30 countries across South America, Asia and Africa, mostly in developing countries including the Carter Center's program in South Sudan.[52]

He has actively engaged the transformation of DNA sequencing from the days of reading radioactive traces by-eye to the current next-gen (NGS) frameworks and their myriad applications. At the Institute of Comparative Genomics, Siddall spearheaded the build-out the NGS program at the American Museum of Natural History while pushing for a bioinformatics team as a community resource. He has sequenced whole animal genomes from scratch (i.e., unguided “de novo”) leveraging Illumina, Moleculo, and PacBio for the Bed Bug genome, and most recently 10x Genomics for the whole genome of the Medicinal Leech.[53] His published work includes RNAseq transcriptomics, much of which is tissue-specific (e.g., anticoagulants in salivary gland cells of blood-feeding vectors).[53]

Siddall's research ranges from genome-wide screens of tuberculosis against immune system reporter genes to deep metagenomic assessments of biodiversity and their associated microbiomes.[4] He has innovated on environmental DNA (eDNA/iDNA), metagenomics and high-resolution scientific imaging,[4] much of which was translated for public consumption in the award-winning exhibition (Picturing Science).

He has published extensively on leech systematics.[54][55][56]
