Siddall denied the claim.<ref name="auto"/>
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.<ref name = "ECintro">{{cite web|url=https://www.explorers.org/events/detail/public_lecture_series_with_mark_siddall|title=Public Lecture Series with Mark Siddall - The Bloodsucker Proxy: Terrestrial Leeches and Revolutionary New Techniques For Genetic Forest Sampling|author=The Explorers Club|date=2018-04-30}}</ref> In addition to over 160 peer reviewed publications,<ref name = "SiddallScholar">{{cite web|url=https://scholar.google.com/citations?user=e3xDoBMAAAAJ&hl=en|title= Google Scholar Profile for Mark Siddall|date=|accessdate=2021-03-12}}</ref> he is author of the whimsical<ref name = "ECintro"/> book “Poison: Sinister species with deadly consequences”.<ref>{{cite web|url=https://www.google.com/books/edition/Poison/4PVBmQEACAAJ?hl=en |title=Poison: Sinister Species with Deadly Consequences - Mark Siddall - Google Books |publisher=Google.com |date= |accessdate=2021-03-12}}</ref>
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.<ref name = "ECintro"/> 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<ref name = "ECintro"/> in collaboration with President [[Jimmy Carter]].

After completing his PhD in 1994, Siddall started a postdoc at the [[Virginia Institute of Marine Science]] under the supervision of Eugene Burreson.

In 2016, Siddall, [[Jonathan Eisen]], and others were involved in the Twitter controversy #ParsimonyGate.<ref name=":0"/>
Siddall took over stewardship of the museum's summer Research Experiences for Undergraduates Program in 2000 shepherding it through uninterrupted National Science Foundation Grant funding for two decades. 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.<ref name=":0">{{Cite web|last=Siddall|first=Mark|date=2019-08-28|title=REU SITE: Systematics, Evolution and Conservation for the 21st Century|url=https://marksiddall.net/wp-content/uploads/2021/04/siddallnsfreu8.28.2019.pdf|url-status=live}}</ref> Siddall is known for matching the representation of women (71%) and minorities (31%) in the program to the proportions of those applying.<ref name=":0" /> Fully 39% of the interns he admitted into the program are in tenure track faculty positions among whom women represent 67%.<ref name=":0" /> Among his former interns are [[Lauren Esposito]] at the California Academy of Sciences and [[Anna J.

The [[American Museum of Natural History]] fired Siddall in September 2020 for alleged [[sexual harassment]], citing museum policy that prohibits sexual relationships between staff and mentees under their academic supervision.<ref name="auto" /> An outside law firm representing the museum's interests found that Siddall had "engaged in verbal, written, and physical conduct of a sexual nature that had the effect of unreasonably interfering with your academic performance."<ref name="auto" /> Siddall denied that any sexual encounter ever took place, and claimed he was fired because "he had found a serious error" in a paper.<ref name="auto" />

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.

Latest revision as of 09:17, 7 April 2024

Mark E. Siddall is a Canadian biologist and former curator[1] at the American Museum of Natural History. Siddall has studied the evolution and systematics of blood parasites and leeches, and systematic theory[2].[citation needed] Siddall was hired as an assistant curator at the American Museum of Natural History in July, 1999[3] and worked there as a curator until September, 2020, when he was terminated for allegedly having violated the museum's policy prohibiting sexual relationships between staff and mentees. Siddall denied the claim.[1]

Education[edit]

Siddall completed a Masters[4] and PhD[5] under the supervision of Sherwin S. Desser at the University of Toronto in 1991 and 1994, respectively.[6]

Career[edit]

After completing his PhD, Siddall completed a postdoc at the Virginia Institute of Marine Science.[7] Subsequently, he was a fellow in the Michigan Society of Fellows from 1996-1999.[8] He also acted as treasurer of the Willi Hennig Society, publisher of the journal Cladistics.[9]

Siddall has worked and published on parasitic and other animals, including leeches,[10] jellyfish,[11] guinea worms,[12] and bed bugs.[13][14]

He is author of the science book Poison: Sinister Species with Deadly Consequences.[15]

In 2016, Siddall, Jonathan Eisen, and others were involved in the Twitter controversy #ParsimonyGate.[9]

The American Museum of Natural History fired Siddall in September 2020 for alleged sexual harassment, citing museum policy that prohibits sexual relationships between staff and mentees under their academic supervision.[1] An outside law firm representing the museum's interests found that Siddall had "engaged in verbal, written, and physical conduct of a sexual nature that had the effect of unreasonably interfering with your academic performance."[1] Siddall denied that any sexual encounter ever took place, and claimed he was fired because "he had found a serious error" in a paper.[1]

Research[edit]

Siddall studies phylogenetics and evolution.[10] Siddall has been described as "a staunch supporter of parsimony and a harsh critic of maximum likelihood approaches”, although "having mellowed a bit on that".[7]
