Welcome to my Website!

I am a postdoctoral fellow in the Advanced Study Program at the National Center for Atmospheric Research. My work focuses on interdisciplinary research, both the physical and social sciences, to better understand our interconnected world and create effective policies. I am very excited to collaborate with NCAR and the rest of the meteorological community to further our understanding of atmospheric science and benefit society. Feel free to contact me!


Curriculum Vitae

Recent Work

Picture
Graduated from the University at Albany with a Ph.D. in Atmospheric Science. 
Picture
Defended my dissertation titled "Synergistic effects of midlevel dry air and vertical wind shear on tropical cyclone development." The picture is with my committee (not pictured: Dr. George Bryan).
Picture
Honor: Received the University at Albany Bernard Vonnegut Teaching Award. 
Picture
Outreach: Participated in the miSci Science Festival of the Capital Region. We conducted fun weather activities with young scholars to excite interest in science! 
Picture
Participated as a Flight Scientist on a P-3 mission into Tropical Storm Gordon with Hurricane Hunters and HRD scientists. 

More pictures are on the HRD blog HERE.
Picture
Spent the summer at NCAR collaborating with Dr. George Bryan on my dissertation research through the ASP Graduate Visitor Program.
Picture
Advocated for basic science research funding with UCAR PACUR members at Capitol Hill. 

University news article about this experience can be found HERE.
Picture
Presented at the 33rd Conference on Hurricanes and Tropical Meteorology. 

Title: Synergistic Effect of Mid-level Dry Air and Vertical Wind Shear on Tropical Cyclone Ventilation Pathways

Summary: Mid- and low-level ventilation have specific 3D structures, both of which have implications for inhibiting convection.
Picture
Published a first-authored peer-reviewed journal article.

Title: Effect of Midlevel Dry Air on Development of the Axisymmetric Tropical Cyclone Secondary Circulation

​Summary: Midlevel dry air is transported into the subcloud layer by the downward branch of the secondary circulation, acting to decrease both the radial width of convection and the net upward vertical mass flux in simulated tropical cyclones. 
Picture
Presented at the 8th Tropical Meteorology Workshop.

Title: Synergistic Effect of Midlevel Dry Air and Vertical Wind Shear on the Development of the Tropical Cyclone Secondary Circulation 

​Summary: Midlevel ventilation near the circulation center is presumed to inhibit development. The secondary circulation is stronger for moister simulations with weaker vertical wind shear. 
Picture
Outreach: Participated in our annual Family Earth Day event to spread science knowledge to the community! I dressed up as a "Weather Friend." These types of outreach activities are my favorite part of being a scientist! 
Picture
Presented at UAlbany's College Teaching Symposium. 

Title: Framing a Growth Mindset: Change What Happens in your Classroom
Picture
Presented a research project for ATM 741: Special Problems in Tropical Cyclone Research.

Title: The Role of African Easterly Waves North of the African Easterly Jet on Tropical Cyclogenesis

Summary: Waves north of the African easterly jet can merge with waves south of the African easterly jet and positively contribute to tropical cyclogenesis.

Picture
Presented at the 32nd Conference on Hurricanes and Tropical Meteorology.

Title: Sensitivity of Tropical Cyclone Spinup Time and Convection to the Initial Entropy Deficit

Summary: Dry mid-level air is transported into the subcloud layer, acting to decrease both the radial width of convection and the net upward vertical mass flux in simulated tropical cyclones.

Picture
Co-Chair and Session Chair of the 2015-2016 AMS Student Conference Planning Committee.

Served as one of the main organizers of the AMS Student Conference. The agenda for this conference can be found HERE.


Picture
Presented a talk at the 17th Cyclone Workshop. The talk link can be found HERE.

Title: Sensitivity of Convection to the Initial Entropy Deficit

Summary: Dry air entrainment into the PBL reduces the mean upward vertical mass flux and increases the spinup timescale of a simulated tropical cyclone.
Picture
Presented a poster at the 14th Annual AMS Student Conference.

Title: Investigating the Role of Tropospheric Water Vapor on Tropical Cyclone Development

Summary: Quantified the necessary mid-level moistening before TC development.

Picture
Published an article to "Physics Today" based on research from Dr. Kristen Corbosiero's TC class.

Title: The Role of Water Vapor in Tropical Cyclone Development

Summary: Quantified the necessary mid-level moistening before TC development.
