Nantucket Maria Mitchell Association Welcomes Dr. Valerie Hall Featured Guest for August Science Speaker Series

August 2, 2023

NANTUCKET, MA—The Nantucket Maria Mitchell Association (MMA) announces that it will host Dr. Valerie Hall, Ph.D., as a featured presenter for its Science Speaker Series. Her presentation will take place on August 16 at 6 pm. It will be presented in-person at the MMA Research Center at 2 Vestal Street and via Zoom. This event is free to all.


This feature presentation will give an overview of the biology of the bay scallop and its unique fishery. Dr. Valerie Hall, Maria Mitchell Research Associate, and nine of her students: Ellie Kinsella and Gray Simanson; Sophia Beni, Gus Simanson, Sayam Thapamagar, James Borthwick, Kate Kinsella, Julia Winsor, and Aiden Haase will first describe the biology of the Nantucket Bay Scallop, Argopecten irradians. This presentation will cover the Bay Scallop classification, habitat, distribution, ecological niche, life cycle, reproduction, timing of spawning, predators, parasites, and environmental hazards the species faces. Students will then describe the laboratory and field program which is now in its eighth year at the Maria Mitchell Association. They will also share their experiences on scallop collecting trips in addition to the process of dissecting and preparing the reproductive tissue for histology (the process by which microscope slides are prepared from thin sections of gonad). Finally, students review their examination of prepared slides to determine the degree of spawning of each collection and co-relate their findings to water temperature. Students not only learn how to collect and analyze data but also to master the biology of this species while they gain experience and skills working as a part of a team in a research laboratory setting.


Dr. Valerie Hall has lived on Nantucket for 46 years. After a 35-year career teaching high school science, mostly on Nantucket, she earned her Ph.D. in Fisheries Oceanography at the University of Massachusetts’ School for Marine Science and Technology in 2014. She then began a research and mentoring program at the MMA which has just completed its eighth summer. During that time, Dr. Hall has worked with over 80 high school and college students alike. Students earn community service hours and have benefitted immensely from Dr. Hall’s program, many of them asking to return for subsequent seasons.

This presentation is complimentary and held both in-person, at the MMA’s Research Center located at 2 Vestal Street, and via Zoom, please pre-register.



The Maria Mitchell Association was founded in 1902 to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. After she discovered a comet in 1847, Mitchell’s international fame led to many achievements and awards, including an appointment as the first female professor of astronomy at Vassar College. Maria Mitchell believed in “learning by doing” and today that philosophy is reflected in the MMA’s mission statement, programs, research projects, and other activities. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, and preserves the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages.

It used to be that whatever the deer or bunnies ate at my home garden, I could plant with relief in Town in the Mitchell House garden. But, over the years, it has become more difficult as we have a plethora of bunnies – multiple complaints made here in this blog – and deer that are now coming into Town year round. They have resorted, in winter, to eating ivy and while ivy is considered invasive, it has been a long-time, reliable ground cover in Town – as in a hundred or more years. Now, we have voles – which do have cycles where their population booms for a year – or two – but we have not had them in the MMA gardens at least in my memory. Now, we do and I worry about them devastating the garden in front of the Observatory which is a large, native species garden we have worked on for many years. I know climate change is definitely playing a role – it’s affecting the birth cycles of voles and allowing them to have potentially more broods. Its also potentially affecting some of their predators that may not be as prevalent and thus fewer voles are being eaten. In any case, we have tunnels galore, which is why I was happy to have ONE blossom on the heirloom morning glories I plant for Mitchell House every spring. Out of 500 or more seeds – I got one lonely blossom! The voles are attacking my own personal garden – the last two summers – and I have lost many of the mainstay lilies and perennials that have been there for forty years – or they have shrunken due to their root systems being undermined and eaten. Roses are failing too. So if anyone has better ideas then solar hummers, live trap, kill trap, or Juicy Fruit gum – let me know – poisons not allowed! JNLF Update: Got four more blossoms - but still!

NANTUCKET, MA— —The Nantucket Maria Mitchell Association (MMA) announces that it will host its new Director of Astronomy, Jackie Mlingo, PhD., as a featured presenter for its October Science Speaker Series. The presentation will take place on Wednesday, October 15 at 7pm in person at the MMA Research Center, 2 Vestal Street, and via Zoom. The event is FREE to all. Have you ever noticed the dark spots that sometimes appear on the Sun’s surface? These “sunspots” are just one example of star spots—mysterious patches that appear on stars across the galaxy. Far from being simple blemishes, star spots reveal the powerful magnetic forces at work inside stars, forces that also drive solar storms and shape the space weather that can impact entire planetary systems. In this talk, Dr. Milingo will share her research on star spots and how she uses them as a window into teaching undergraduates the process of scientific discovery. She will also explore how science can reach far beyond the classroom—bringing STEM into everyday spaces and sparking curiosity across communities, from kindergartners to lifelong learners. Dr. Jackie Milingo is an observational astronomer who earned B.S. degrees in Physics and Astronomy from the University of Kansas, and a Ph.D. in Astrophysics from the University of Oklahoma. Her research is currently focused on understanding magnetic activity cycles in sun-like stars through long-term studies of starpots. Dr. Milingo joins the MMA after a year-long AAAS Science and Technology Policy Fellowship at the U.S. National Science Foundation, where she was a Fellow in the Office of Legislative and Public Affairs, as well as the Astronomy Division in the Math and Physical Sciences Directorate. Before her fellowship, she was a professor in the Physics Department at Gettysburg College for over twenty years where her work included mentoring undergraduate research students. Dr. Milingo joined the staff of the MMA in early September after a year-long, worldwide search for a new astronomer. She becomes the eighth MMA Astronomer and Director of the Astronomy Department of the MMA since Margaret Harwood, the MMA’s first astronomer, served from 1916 to 1957. Dr. Milingo has spent her career committed to generating transformative experiential learning opportunities, contributing to public education and outreach, removing barriers for students, and changing the conversation and learning spaces in astronomy, physics, and STEM in general. This event will be held both in person and via Zoom. Pre-registration is required to attend either option.
