Guido Cervone, Ph.D.

I am Associate professor of Geography, Meteorology and Atmospheric Science and Associate Director of the Institute for CyberScience at the Pennsylvania State University. I am also Affiliate Scientist with the National Center for Atmospheric Research (NCAR) and Adjunct Professor at the Lamonth-Doherty Earth Observatory (LDEO) of Columbia University. My research sits at the intersection of geospatial science, atmospheric science and computer science. My research focuses on the development and application of computational algorithms for the analysis of spatio-temporal remote sensing, numerical modeling and social media Big Data related to environmental hazards and renewable energy. I received research funding from DARPA, NSF, ONR, DOT, NCAR, NASA, Italian Ministry of Research and Education, Draper Labs, Stormcenter Communication.

I am affiliated scientist with the Research Application Laboratory (RAL) at the National Center for Atmospheric Research (NCAR), and adjunct professor at the Lamont Doherty Earth Observatory at Columbia University. In 2013 I received the ``Medaglia di Rappresentanza'' from the President of the Italian Republic for my work related to the Fukushima crisis. I authored two edited books, over forty fully refereed articles relative to data mining, remote sensing and environmental hazards. I co-chaired several workshops on remote sensing, data mining and GeoInformatics. In 2010, I was awarded a US patent for an anomaly detection algorithm. My research was featured on TV news, newspapers, and general interest magazines. I sailed over 4000 offshore miles and I do not own a cell phone.

Martina Calovi

I am a Postdoctoral Research since February 2018 at the Geoinformatics and Earth Observation Laboratory (GEOlab) in the Department of Geography and Institute of CyberScience. I am collaborating with the Grozinger Laboratory, in the Department of Entomology and with the U.S. Department of Agriculture at the Pennsylvania State University.

I obtained my Ph.D. in Change and Complexity Management, in December 2017, at Sant’Anna School of Advanced Studies in Pisa, Italy. The dissertation focuses on bridging geography with healthcare and disaster management. Particular attention was addressed to the use of GIS to support the spatial reorganization of outpatient care services delivery and to understand how much the proximity affects the patient’s choice of specialized cardiological visit in Italy. A third part focused on the use of atmospheric models and private weather stations to generate forecasts in urban areas. The innovative methodology used allowed to downscale the Global Forecast System (GFS) deterministic forecasts model, and to generate deterministic forecasts with a higher spatial and temporal resolution then the input forecast. The methodology has been developed and tested over the Manhattan borough. The overall main goal was to analyze the accessibility to health care services and first aid facilities, in regular conditions and during emergency situations, focusing to the needs of the most vulnerable population.

My research interests cover Geographical Information Science applied to natural disaster and emergencies, climate change, extreme weather events forecast, data fusion, interactions and coexistence between human and physical environment, and the managerial implications of geographical analyses into the decision-making process.

Jian Sun

I am a Postdoctoral research scholar since January 2019 at the Geoinformatics and Earth Observation Laboratory (GEOlab) in the Department of Geography. I’m also collaborating with InSAR Geodesy & Geohazards Laboratory (IGG) in the Department of Geosciences and Dr. Melissa Gervais in the Department of Meteorology and Atmospheric Science in College of Earth and Mineral Sciences and Institute of CyberScience at the Pennsylvania State University.

I obtained my Ph.D. in Exploration Seismology, in May 2018, at University of Calgary in Alberta, Canada. My dissertation focuses on computational and practical developments and implementations of internal multiple prediction (IMP) based on inverse scattering series. The computational burden and challenges of performing IMP in practice drives and inspires me of attempting deep learning (DL) / machine learning (ML) techniques in Earth Science tasks. Particular attention was paid to solve the inverse problems in Exploration Geophysics both in a conventional DL way and in a new paradigm of theory-guided data science. The later approach is to combine conventional DL/ML methods and physics-based characteristics approaches, and to benefit from each other, which allows DL/ML architectures learning from deterministic physics to reduce tremendous amounts of training sets requirement and to resolve other challenges to some extent in Earth Science, in opposite, taking advantages of DL/ML architecture extremely reduces computational cost of physics-deterministic methods by transferring amounts of iterative processes into a direct application.

My current interests includes but not limited to bridge the Earth Science with spatio-temporal DL/ML techniques, for instance, to advance beyond static pattern identification and understand the entire spatio-temporal evolution of Arctic air masses and the resulting cold air outbreaks in a changing climate, to ‘track’ and ‘isolate’ the different deformation signals using DL/ML techniques which would lead to breakthroughs in volcanology with obvious implications in hazards assessment and risks mitigation, to quantify the photovoltaic (PV) energy potential in selected regions of the USA based on future possible climate scenarios.

Ph.D. Graduate Students

Laura Clemente-Harding, M.S.

I am a Ph.D. student in the Department of Geography. I completed my Bachelors degree in Meteorology with an Environmental Inquiries minor in 2007 at Penn State. In 2009, I graduated from George Mason University with my Masters in Earth Systems Science. Since graduate school I have been working for the Engineering Research and Development Center's Geospatial Research Laboratory. This experience, along with an insatiable curiosity, sparked my interest in returning to school to pursue my PhD. My research interest include renewable energies, terrain reasoning, the application of land atmosphere interactions to the decision making process. Outside of school and work, I am also interested in coastal ecosystems and enjoy taking any opportunity to see or travel to marine areas. In my free time, I like to be outdoors. A few of my favorite things are skiing, hiking, camping, and gardening. Email: lec170 AT psu DOT edu

Carolynne Hultquist, M.S.

I am a Ph.D. student specializing in fusing remote sensing and geographic information to better understand complex environments. My research has involved machine learning techniques, the use of geospatial technologies during hazards, energy, and complexity theory. I joined the Geoinformatics and Earth Observation Laboratory to pursue research using computational methods for spatio-temporal analysis of natural disasters. I received my M.S. Geography degree at Penn State for my thesis involving validating radiation measurements around Fukushima by comparing citizen science, government data, and models over space and time. I believe it is critical to recognize the informational benefits and limitations of environmental and social data from various geospatially enabled technologies.

Undergraduate Students

Yu Zhong

My name is Yu Zhong. I’m a undergrad student majoring in GIS. I started taking Guido’s class in 2017 and became interested in image analysis ever since. Currently, I mainly use R to study satellite image on Zimbabwe. Hopefully I’ll acknowledge more R skills and gain more insights of GIS application. Besides using R, I am now learning drones and VR as well. I wish I’ll never stop learning no matter in undergraduate or in the future.
