'''Linsey Chen Marr''' is an American scientist who is a University Distinguished Professor in the Charles E. Via, Jr. Department of Civil and Environmental Engineering at Virginia Tech. Her research considers the interaction of nanomaterials and viruses with the atmosphere.<ref name=":6" /> During the COVID-19 pandemic Marr studied how SARS-CoV-2 and other airborne pathogens could be transported in air.<ref>{{Cite journal|last1=Wang|first1=Chia C.|last2=Prather|first2=Kimberly A.|last3=Sznitman|first3=Josué|last4=Jimenez|first4=Jose L.|last5=Lakdawala|first5=Seema S.|last6=Tufekci|first6=Zeynep|last7=Marr|first7=Linsey C.|date=2021-08-27|title=Airborne transmission of respiratory viruses|journal=Science|language=en|volume=373|issue=6558|article-number=eabd9149|doi=10.1126/science.abd9149|pmid=34446582|pmc=8721651|issn=0036-8075}}</ref> In 2023, she was elected to the National Academy of Engineering and named a MacArthur Fellow.<ref name=Mac>{{Cite web |title=Linsey Marr |url=https://www.macfound.org/fellows/class-of-2023/linsey-marr |access-date=2023-10-05 |website=www.macfound.org |language=en}}</ref>

== Research and career == Marr joined the faculty at Virginia Tech in 2003, where she established her own research group that investigates how engineered nanomaterials interact with the atmosphere.<ref name=":1"/> Marr showed that when released into the air, engineered nanomaterials can aggregate with other matter to form structures of various sizes (in the nm and μm length scales).
Beyond nanomaterials, Marr has considered how airborne pathogens pollute the atmosphere. To Marr, airborne pathogens are self-replicating assemblies of nanoparticles. In 2013 she was awarded a National Institutes of Health (NIH) New Innovator award to study virus transmission by bioaerosols.<ref name=":3">{{Cite web|url=https://www.vtnews.vt.edu/content/vtnews_vt_edu/en/articles/2013/10/100113-engineering-linseymarrnihaward.html|title=National Institutes of Health New Innovator Award to study flu virus goes to Linsey Marr|website=www.vtnews.vt.edu|language=en|access-date=2020-04-22|archive-date=2021-01-17|archive-url=https://web.archive.org/web/20210117163016/https://vtnews.vt.edu/content/vtnews_vt_edu/en/articles/2013/10/100113-engineering-linseymarrnihaward.html}}</ref> Her early research considered the spread of influenza, looking at the viral concentration in the air of aeroplanes and play centres.

In an effort to establish the dynamics of these pathogens, Marr has developed sensitive, multi-layer sensors. The sensors include a custom-DNA that has been designed to immobilise specific viruses, which are subsequently bound to another DNA strand which can be attached to a gold nanoparticle for viral detection using Raman spectroscopy.
Alongside virus transmission and nanomaterial – atmosphere interactions, Marr has investigated the emissions and transport of air pollutants.<ref name=":4">{{Cite web|url=https://www.vtnews.vt.edu/content/vtnews_vt_edu/en/articles/2018/05/eng-harr-lunsford-professor.html|title=Linsey Marr appointed Charles P.

Marr had long doubted the correctness of the World Health Organization advice on transmission of viruses by aerosols, namely that the line between droplets and aerosols should be drawn at 5 microns, commenting "The physics of it is all wrong", and claiming that particles much larger than 5 microns could stay afloat and behave like aerosols, depending on humidity, heat, and air speed. In 2010 she installed air samplers in day care centres and airplanes and found flu viruses in the air, in small particles which had stayed in the air for hours.<ref name=MM>Megan Molteni, [https://www.wired.com/story/the-teeny-tiny-scientific-screwup-that-helped-covid-kill/ "The 60-Year-Old Scientific Screwup That Helped Covid Kill"] {{Webarchive|url=https://web.archive.org/web/20210522214601/https://www.wired.com/story/the-teeny-tiny-scientific-screwup-that-helped-covid-kill/ |date=2021-05-22 }}, ''Wired'', 05.13.2021, accessed 25 May 2021</ref>
In January 2020, Marr reviewed a research paper by Yuguo Li which found that the long-established 5-micron boundary was fallacious and that most flu, colds, and other respiratory illnesses spread through aerosols, and not droplets. She wrote of it "This work is hugely important in challenging the existing dogma about how infectious disease is transmitted in droplets and aerosols." In October 2020, Marr was a co-signatory of a letter in ''Science'' urging epidemiologists to abandon the 5-micron threshold.<ref name=MM/>

On April 30, the WHO changed its online advice on the transmission of COVID-19, accepting that it can spread by aerosols as well as larger droplets, and Zeynep Tufekci reported in The New York Times that a big news story had passed almost unnoticed. The Centers for Disease Control and Prevention also made changes to CDC guidance, placing the inhalation of aerosols at the top of its list of how COVID-19 spreads.<ref name=MM/>
