Details
Increasingly common hotter and drier conditions cause drought stress on plants. The response of plants to these conditions is a significant source of uncertainty in hydrologic and water resources predictions, climate change forecasts, and wildfire risk estimates, among others. However, characterizing plant responses to water stress is challenging because of the large diversity of relevant vegetation traits (including root, xylem, and stomatal properties) within species, within ecosystems, and across the globe.
Alexandra Konings, associate professor of Earth system science at Stanford, will describe how remote sensing (i.e., satellite measurements) of vegetation water content—which naturally integrates over these sources of variability and provides data across the globe—may be a useful tool for better understanding plant water stress response. After describing the scientific challenges in quantifying plant-water stress, Konings will introduce microwave remote sensing and what data it can provide. She will then discuss several examples of the utility of this data: including for accounting for spatial variability in ecosystem behavior and better predictions of hydrologic cycle, and for understanding wildfire risk under different conditions. She'll also briefly discuss emerging frontiers and opportunities.
This event is for: alumni, community connections, faculty, staff, students
Community Connections events provide opportunities for HMC faculty, students and staff to cultivate community, foster open conversations and share important information as together we live out our mission and shape the future of the College.
Calendars
The Cabinet is hosting informal coffee breaks in fall 2025 for students, faculty, and staff. These coffee breaks will be attended by most of the Cabinet team and will provide an opportunity for the community to share ideas, express concerns, and highlight successes.
All are welcome to stop by as schedules allow.
“We don’t want to live in a society in turmoil. In the US, 93 percent of people want to reduce divisiveness, and 86 percent believe it’s possible to disagree in a healthy way. Yet with increasing political and social fragmentation, many of us don’t know how to move past our differences. Civil rights scholar john a. powell presents an actionable path through “bridging” that helps us communicate, coexist, and imagine a new story for our shared future where we all belong.” (taken from Othering and Belonging Institute)
The Office of Civic & Community Engagement (OCCE) will be hosting a guilt-free book club this fall semester on john a. powell’s book The Power of Bridging: How to Build a World Where We All Belong. Our first gathering is on Friday, October 3rd.
This learning community is for everyone, from those who are already experienced in community engagement to those who are curious about learning more about this high-impact educational practice. Faculty participants will discuss readings, meet with outside speakers, share ideas, and think collaboratively about implementing community engagement into the 5C students’ experience.
Welcome to HMC’s Community Conversations for the fall 2025.
HMC Community Conversations* use conversation guides with a structured format to help people with different viewpoints and experiences build understanding. There will be 3–5 other people in a table group. It is not a debate, and the goal is not to change one another’s opinions. There are Conversation Agreements like “Listen and Be Curious” and “Show Respect and Suspend Judgement” that create the framework for diving into the questions. The questions are designed to draw out our personal experiences rather than opinions around the topic.
The overall purpose is to learn more about the experiences others have around the topic and build a sense of community.
Community Conversations will take place on Tuesdays from 11 a.m. to noon in Shanahan 1480; and each gathering will be on a separate topic. Gatherings will be in person only.

Understanding the controlling factors behind the chemical composition of the Earth’s atmosphere is a critical step toward addressing the modern environmental challenges of air pollution and climate change. Traditional methods interrogating theoretical predictions with observations have been highly successful in addressing these challenges, particularly in light of the recent immense growth of data availability in environmental systems. However, there are still gaps in our scientific knowledge due to limitations in modern scientific techniques (e.g., theoretical frameworks, observational systems, and computational power). Data-driven methods from the data science and artificial intelligence literature, when informed and guided by scientific understanding, present a valuable tool in addressing these knowledge gaps.
Sam Silva, assistant professor of Earth sciences, civil and environmental engineering and population and public health sciences at USC, will present results from recent work using a variety of data science and A.I. methods to better constrain modern understanding of atmospheric chemistry and composition.
