:Ashley Walker (astrochemist)

Walker was raised in Chicago's Englewood neighborhood where she developed an interest in science, enjoying visits to the Adler Planetarium.{{Cite web|last=Fredette|first=Meagan|date=December 14, 2020|title=Astrochemist Ashley Lindalía On The Importance Of Fostering More Diversity In STEM|url=https://www.bustle.com/rule-breakers/astrochemist-ashley-lindalia-on-the-importance-of-fostering-more-diversity-in-stem|url-status=live|archive-url=https://web.archive.org/web/20201215164352/https://www.bustle.com/rule-breakers/astrochemist-ashley-lindalia-on-the-importance-of-fostering-more-diversity-in-stem |archive-date=2020-12-15 |access-date=|website=Bustle}} Despite this interest in science, she pursued a degree in business at City College of Chicago, eventually changing her major to forensic chemistry and transferring to Chicago State University. There, she became the university's first to develop her own astrochemistry major, training and collaborating with planetary scientists and computational chemists to study the chemical compositions of planetary atmospheres.{{Cite web|last=Rockett|first=Darcel|date=July 25, 2019|title=Wakandacon returns to Chicago without 'Black Panther.'

She later worked as a research assistant at the Goddard Space Flight Center where she was able to study the atmospheric composition of Saturn's moon Titan using infrared spectroscopy under the mentorship of planetary scientist Carrie Anderson.{{Cite web|title=Goddard Center for Astrobiology|url=https://astrobiology.gsfc.nasa.gov/students.html|access-date=2021-01-24|website=astrobiology.gsfc.nasa.gov}}

Walker has leveraged her social media platforms and networks within astronomy and planetary sciences to advocate for Black women and nonbinary individuals pursuing careers in science, technology, engineering, and mathematics (STEM). In 2019, she organized an event at the Adler Planetarium to highlight Black women in astrochemistry and planetary sciences as part of the Wakandacon convention. Building on the success of Black Birders Week, an online campaign that highlighted Black nature enthusiasts and increased the visibility of Black birders, Walker co-organized #BlackInAstro, #BlackInChem, and #BlackInPhysics weeks.{{Cite web|last=Kwon|first=Karen|date=June 25, 2020|title=Black Astronomers Highlight Achievements and Obstacles|url=https://www.scientificamerican.com/article/black-astronomers-highlight-achievements-and-obstacles/|url-status=live|archive-url=https://web.archive.org/web/20200625190719/https://www.scientificamerican.com/article/black-astronomers-highlight-achievements-and-obstacles/ |archive-date=2020-06-25 |access-date=|website=Scientific American|language=en}}{{Cite web|last=Rabie|first=Passant|date=|title=#BlackInAstro highlights the experiences of Black astronomers: "We don't see us in the room."|url=https://www.inverse.com/science/black-astronomers-experience|url-status=live|archive-url=https://web.archive.org/web/20200611055553/https://www.inverse.com/science/black-astronomers-experience |archive-date=2020-06-11 |access-date=|website=Inverse}}{{Cite web|last=Mallenbaum|first=Carly|date=August 4, 2020|title=#BlackBirdersWeek, #BlackInNeuro: Black scientists, physicians are using hashtags to uplift|url=https://www.usatoday.com/story/life/2020/08/04/blackinneuro-blackinchem-can-hashtags-help-black-scientists-build-community-spotlight-excellence/5541431002/|url-status=live|archive-url=https://web.archive.org/web/20200805003112/https://www.usatoday.com/story/life/2020/08/04/blackinneuro-blackinchem-can-hashtags-help-black-scientists-build-community-spotlight-excellence/5541431002/ |archive-date=2020-08-05 |access-date=|website=USA Today|language=en-US}}{{Cite web|last=Harris|first=Margaret|date=2020-10-29|title=Celebrating Black physicists|url=https://physicsworld.com/a/celebrating-black-physicists/|url-status=live|archive-url=https://web.archive.org/web/20201101044202/https://physicsworld.com/a/celebrating-black-physicists/ |archive-date=2020-11-01 |access-date=2021-01-03|website=Physics World|language=en-GB}} In addition to highlighting Black scientists leading in those fields, the campaigns also advocated for eliminating graduate programs' reliance on the Graduate Record Examinations (GREs) and highlighting internships, funding support, and other career development opportunities for early career Black researchers.{{Cite web|last=Martin|first=Kristyn|date=July 1, 2020|title=The surprising reasons there are so few Black scientists in the space industry|url=https://www.yahoo.com/lifestyle/the-surprising-reasons-there-are-so-few-black-scientists-in-the-space-industry-191326471.html|url-status=live|archive-url=https://web.archive.org/web/20200701195728/https://www.yahoo.com/lifestyle/the-surprising-reasons-there-are-so-few-black-scientists-in-the-space-industry-191326471.html |archive-date=2020-07-01 |access-date=|website=Yahoo Life}} The inaugural #BlackInChem produced content in collaboration with the Royal Society of Chemistry and the American Chemical Society, while #BlackInAstro partnered with the American Astronomical Society's Astrobites to produce curated content for the week.{{Cite web|last=|first=|date=October 16, 2020|title=#BlackinChem part 1: #BlackinChem week|url=https://www.rsc.org/news-events/profiles/2020/oct/blackinchem-pt-1/|url-status=live|archive-url=https://web.archive.org/web/20201019041711/https://www.rsc.org/news-events/profiles/2020/oct/blackinchem-pt-1/ |archive-date=2020-10-19 |access-date=2021-01-06|website=Royal Society of Chemistry|language=en-GB}}{{Cite web|last=Kohler|first=Susanna|date=June 10, 2020|title=#BlackInAstro: How Can We Support Black Astronomers?|url=https://aasnova.org/2020/06/10/blackinastro-how-can-we-support-black-astronomers/|url-status=live|archive-url=https://web.archive.org/web/20200611054101/https://aasnova.org/2020/06/10/blackinastro-how-can-we-support-black-astronomers/ |archive-date=2020-06-11 |access-date=2021-01-06|website=aasnova.org|language=en-US}} These campaigns were collectively recognized by the journal Science as a finalist for 2020 Breakthrough of the Year.{{Cite web|last=Langin|first=Katie|date=2020-12-21|title='A time of reckoning.'

While an undergraduate, she lost her father, Kenneth Lovell, to lung cancer.{{Cite web|last=Elgas|first=Rob|date=2016-12-30|title=College student's future in danger after she's mistakenly declared dead|url=https://abc7chicago.com/1678667/|access-date=2021-01-20|website=ABC7 Chicago|language=en}} After his death, she was mistakenly declared dead because she was listed as an informant on his death certificate, which placed her financial aid for college in jeopardy. She was able to raise over $8,000 in donations to complete her spring semester, as well as a summer fellowship at Harvard University.{{Cite web|last=Anderson|first=Tom|date=2017-01-12|title=You may be dead: Every year, Social Security falsely lists 6,000 people as deceased|url=https://www.cnbc.com/2017/01/12/social-security-falsely-lists-6000-people-a-year-as-dead.html|access-date=2021-01-20|website=CNBC|language=en}}
