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" />

==Research==

Siddall studies phylogenetics and evolution.<ref name=Zimmer/> 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".<ref name="auto2">{{Cite journal|title=Society Business|author1=Burreson, Eugene M.|author2=Siddall, Mark E.|author3=Connors, Vincent A.|year=2002 |journal=The Journal of Parasitology|volume=88 |issue=6|pages=1053–1070|doi=10.1645/0022-3395(2002)088[1053:IOMESA]2.0.CO;2|jstor=3285473|pmid=12537094 |s2cid=44766356 }}</ref>
