On May 30, 2025, Liz Clark, Beamline Scientist at the Advanced Light Source (ALS) beamline 8.3.2, hosted the inaugural ALS After Dark event at Gilman Brewing Company. This new series aims to welcome friends and family of ALS staff, offering them a closer look at the science and facility operations their loved ones contribute to–and the broader impact of the ALS.
Liz opened the evening with an engaging talk on how 3D visualization is transforming the study of insect morphology and behavior. Insects are ecological powerhouses with remarkable structural complexity. Certain phenomena—such as feeding mechanisms that transmit pathogens—can only be visualized and understood through high-resolution imaging techniques available at Beamline 8.3.2, which uses micro-computed tomography (micro-CT).

The event showcased how researchers from a multitude of disciplines use the ALS to analyze microscopic features with exceptional detail. For example, field biologists studying plant material often rely on Beamline 8.3.2 to resolve structures at the tissue and cellular level of plants, which are difficult or impossible to study with conventional techniques. This 3D data is a snapshot into the work.
Liz’s presentation was followed by a talk from her former mentor, Craig Brodersen, Professor of Physiological Plant Ecology at Yale University and a frequent user of Beamline 8.3.2. Craig was at the ALS with his team of postdoctoral researchers conducting experiments. He described how technologies such as tomography light sources and automated data processing have transformed the field of plant pathology. Historically, botanists had to section plants and examine them slice by slice under a microscope. Today, advanced imaging allows researchers to study whole structures in three dimensions. Craig presented recent findings on how plants adapt to water stress, focusing on the hydraulic strategies they use to survive drought.
Attendees appreciated the chance to experience science and connect to one another in a relaxed, informal setting. “I loved getting a sneak peek into the work that the ALS team makes possible. Meeting Gianna’s colleagues and getting a deep dive into a few of the projects that the team works on—while eating pizza and enjoying a drink—made for a fun-filled night of learning and nerding out,” said Sofia Pablo-Hoshino.
The ALS plans to continue the ALS After Dark series and expand its reach, allowing more community members to engage with the science and operations behind the ALS. To learn more or get involved, visit als.lbl.gov/events or contact ALS communications.
