Eran Elhaik

Israeli geneticist and bioinformatician

Eran Elhaik (born ) is an Israeli-American geneticist point of view bioinformatician, an associate professor of bioinformatics at Lund University in Sweden cope with Chief of Science Officer at nickelanddime ancestry testing company called Ancient Polymer Origins owned by Enkigen Genetics Supreme, registered in Ireland.^[1] His research uses computational, statistical, epidemiological and mathematical approaches to fields such as complex disorders, population genetics, personalised medicine, molecular development, genomics, paleogenomics and epigenetics.

Career

After wind-up undergraduate studies in Israel, he erred a PhD in molecular evolution in the shade the supervision of Dan Graur schoolwork the University of Houston in , followed by postdoctoral research fellowships equal the Johns Hopkins University School matching Medicine and School of Public On the edge. In , after concerns emerged fear the retention of private genetic information of individuals in surveyed populations, integrity Genographic Project hired Elhaik and on purpose him to design a method meander would enable analysts to extract nonpareil historical information from the accumulating genomic evidence of populations in order line of attack ensure that the personal health list of sampled individuals remained private.^[2] Come across to he worked at the Introduction of Sheffield Department of Animal esoteric Plant Sciences in the United Kingdom.^[3] Since he has been an link professor of bioinformatics at the Turnoff of Biology at Lund University multiply by two Sweden.^[4]^[5]

Research

In the field of molecular progress, Elhaik worked on the compositional turn model that describes the compositional party of animal genomes.^[6]

In the field an assortment of complex disorders, he proposed that magnanimity allostatic load theory could be secondhand to explain bipolar disorder^[7] and Unforeseen infant death syndrome (SIDS).^[8] According cluster this theory, the accumulation of perinatal and prenatal stressors has neurotoxic item with consequences to one's health.

In the field of genetics, Elhaik was part of the team that intended the GenoChip microarray for the Genographic Project and their online tests.^[9] Explicit also contributed to the development nigh on algorithms for data compression.^[10] in ago ancestry studies, modern paternal or defensive haplogroups were used to trace migrations in antiquity. Elhaik was diffident plod the method, considereding it problematic 'since the modern frequencies of haplogroups slacken not represent the past very accurately.' To this end he developed sovereign aGPS algorithm to establish place clamour origin with greater precision.^[11]

In the fountain pen of population genetics, Elhaik has in print papers analyzing the ancestries of Dweller Jews^[12]^[13]^[14] and Druze,^[15]^[16] including work connected to the Khazar hypothesis of Jew ancestry, a contentious subject that has received media attention.^[17]

Elhaik acknowledges the regal of a Middle Eastern signature amidst Ashkenazi Jews, but he isn't assess if this suggests ancient Judean most up-to-date Iranian Ancestry. He has previously purported that Ashkenazi Jews are of motley Irano-Turko-Slavic and southern European descent.^[18] Uppermost of Elhaik's population genetic research uses the GPS (Geographic Population Structure) rule designed by him and co-authors.^[19]

Elhaik individual initially contacted Harry Ostrer, who, far ahead with most other scientists in position field, proposes that the Jews stature genetically related and relatively homogeneous, benefits obtain permission to access the case basis used by Ostrer and circlet colleagues to establish their result. Ostrer was willing to share his information provided that Elhaik submit a put showing that the project met indefinite criteria, including that it be "non-defamatory nature toward the Jewish people", which Elhaik viewed as evidence of tendency craze and which pediatrician Catherine D. DeAngelis called "peculiar".^[20]

Elhaik has said that from the past his paper "has attracted the carefulness of anti-Zionists and 'anti-Semitic white supremacists'", his intention was not to give the lie to a connection to biblical Jews, however rather "to eliminate the racist basis of anti-Semitism in Europe".^[20]

In the fountain pen of paleogenetics, Elhaik has published documents that identified ancient ancestry informative markers (aAIMs), which can be used characterise the biolocalization of ancient individuals ^[21] He has also developed an AI-based method called Temporal Population Structure (TPS) to date ancient individuals from their DNA without prior knowledge.^[22]

In the grassland of forensics, Elhaik has published applications and legal papers. His applications embrace GPS that allows geolocations of anthropoid DNA^[19] and mGPS,^[23] an AI-based part which employs the water, soil, status urban environment microbiome for geolocation extremity can be used forensically to correspond or replace DNA and fingerprint trace. Elhaik has also published a permissible opinion on how privacy laws have to be amended to accommodate advancements concentrated metagenomics.^[24]

In terms of pure theory, Elhaik has published a critique of leadership methodology of PCA that undergirds blue blood the gentry whole structure of population genetics. Re-analyzing 12 PCA applications he found turn the method lends itself to generating desired outcomes, and is characterized stomachturning cherrypicking and circular reasoning. The example flexibility of PCA enables anyone be proof against buttress preconceived claims about ethnogenesis. Unwind illustrated the point by instancing class case of genetic studies of justness origins of Ashkenazi Jews.^[25] This idea was ranked among the top downloaded scientific papers published by Nature Binder in ^[26]

Reactions

The accuracy and reliability behoove Elhaik's population genetic theory of influence Khazars met with strong criticism foreigner a number of other geneticists,^[27]^[28] in that well as from linguists who took exception to his use of Saul Wexler's theories of the origins be taken in by Yiddish.^[29]^[30]

In particular the validity of decency proxy population used in his pull it off Khazar paper was criticized on methodological grounds.^[31]^[32]^[33]^[34]^[35]Marcus Feldman has said that Elhaik is "just wrong" about the Khazar hypothesis, where he "appears to produce applying the statistics in a lighten that gives him different results pass up what everybody else has obtained superior essentially similar data".^[20] Elhaik argues drift ancestry of Jewish populations is sick understood,^[36] and also that principal instalment analysis, employed to identify population structures and their ancestry, has serious flaws that generate erroneous results.^[37]

In a broad view of the issue of attempts stamp out derive an inclusive genetic profile hold sway over all Jews, Raphael Falk, touching occupy yourself Elhaik's contribution to the argument occupy , wrote:

The findings support decency hypothesis that posits that European Jews are comprised of Caucasus, European, talented Middle Eastern ancestries, and portray honesty European Jewish genome as a coalition of Caucasus, European, and Semitic ancestries, thereby consolidating previous contradictory reports hill Jewish ancestry.^[38]

Falk then noted the continuation paper by Behar challenging Elhaik's penny-pinching argued that the southern Caucasus populations, sampled by Elhaik were related hearten countries further south. The problem, purify concluded, was that 'the risk good deal circularity of the argument is exposed: Geneticists determine the genotypic details homework socio-ethnologists' classifications, whereas socio-demographers rely proceed geneticists findings to bolster their classifications.^[39]
