Guido Cervone, Ph.D.

I am Associate professor of GeoInformatics in the Department of Geography and Institute for CyberScience at the Pennsylvania State University. I serve as Associate Director of the Institute for CyberScience. 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 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.

Liping Yang, Ph.D.

Since Fall 2016, I am a Postdoctoral Scholar with the GeoVISTA Center and with the Geoinformatics and Earth Observation Laboratory in the Department of Geography at Penn State. I received my Ph.D. in Spatial Information Science and Engineering from the University of Maine in 2015. Before joining Penn State, I was a postdoctoral researcher in the School of Computing and Information Science at University of Maine, and my research focused on computer vision and point cloud processing for indoor scenes.

My research interests include Geographic Information Science (GIS) , knowledge discovery and representation, algorithms, as well as indoor spaces and indoor navigation. My research focuses are VR in GIS, visual analytics with a focus on integrating and reasoning with heterogeneous information, and high performance computing for earth/environmental science problems (e.g., environmental hazards and renewable energy) using machine learning and big data techniques.

Ph.D. Graduate Students

Laura Clemente-Harding

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.

Elena Sava

I’m a Ph.D. student studying under Guido Cervone. My background is in Global and Environmental Change, which uses remote sensing and related geoinfomation technologies in detecting changes of the Earth’s systems — specifically, the interaction of the geosphere, atmosphere, ecosphere, and sociosphere within local, regional, and global scales. My interests include geographical information science (GIS), remote sensing, environmental hazards, human and physical geography, climate change, and environmental policy. My previous research involved a quantitative analysis of Chlorophyll blooming associated with the Japanese 2011 tsunami using remote sensing satellite data. Currently, my focus is on the fusion of remote sensing and social media data during emergency events such as flooding. For decades remote sensing has been used to make a substantial contribution in emergency situations and damage assessment. However, despite the immense quality of data available, geo-temporal gaps are often present due to limitation of the platform such as revisiting time, atmospheric conditions or other obstruction. The goal is to use social media data and other non-authoritative sources and fill in the gaps in remote sensing observations.

Carolynne Hultquist

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. My research interests include remote sensing, VGI, data mining, geovisual analytics, spatial cognition, emergency management, and public policy.

Yanan Xin

I am a PhD student in the four-year track at Penn State Department of Geography. I got my master of Urban Spatial Analytics from University of Pennsylvania. After graduation, I worked as a GIS Development Intern at DDOT. Then I found my heart was still in the academic world which prompted me to go back to campus. I am a data-driven person and I am fascinated about digging into spatio-temporal data and building numerical models. My previous research includes Local Indicators of Spatio-Temporal Association for Network Constrained Data, Rethink of Curb Parking Demand-based Pricing in San Francisco and Remote Sensing Image Fusion Method Based on Wavelet Transform. With Prof. Cervone’s guidance, I am looking forward to building my kaleidoscope to explore immense spatio-temporal data and solve problems in transportation, environmental hazards, energy and so on. My research interests include spatio-temporal data mining, data fusion, spatial statistics, social and economic networks.

Weiming Hu

I am a Ph. D student in the five-year track graduate program in the department of Geography at the Pennsylvania State University. I completed my bachelor degree in the School of Remote Sensing and Information Engineering at Wuhan University. And now I’m under the advising of Dr. Guido Cervone. My main interest lies in applying remote sensing techniques to monitoring natural disasters and emergencies. Some related topics are 1) image processing and 2) social network data mining. Last year, I participated into a course on fixed-wing UAV (Unmanned Aerial Vehicle) and found that I have great a passion to learn more. Especially to learn about the multi-motor type of UAVs in order to incorporate new techniques into my future projects. Although satellites are getting higher spatial and spectral resolution and we are obtaining more data than ever with remote sensing, the real-world problems are even more complex and inter-related. Thus with the help of GIS technology, I’m able to touch and recognize the inner beauty of this world in which we live.
