Introduction

Hello, my name is Alexander Savelyev. I am also commonly known as Sasha, which is a proper diminutive of my first name in Russian. I am a fourth-year PhD student at the Department of Geography at the Pennsylvania State University.

My academic career began with an application to the Department of Geography at the Saint-Petersburg State University (SPSU), Russia. I was at the time (and still am) fascinated by the complexity, scale and variety of the phenomena that are addressed by this discipline. After receiving my Bachelors in cartography from SPSU I came to the University of Northern Iowa (UNI) and spent some time there working on my Masters degree (I did my Masters thesis on thermal infrared remote sensing). Over the years that I spent at SPSU and UNI I received extensive training in various sub-disciplines of geography, cartography, GIS, SDSS, remote sensing and computer science. It is this fusion between the disciplines of geography and computer science that brought me to the Doctorate program at the Pennsylvania State University.

Summary of interests

My current research interests generally revolve around the unique ability of maps to generate, convey and emphasize spatial knowledge. Coupled with my interest in computer science topics, this brought me to the realm of geovisualization and geovisual analytics. A large part of my work as a Research Assistant at PennState is related to SensePlace2, an interactive web-based environment for Social Media analytics. Over the period of the last three years, I have developed a number of components for the SensePlace2 user interface and now occupy the position of its chief UI developer. This experience introduced me to a range of cutting-edge visualization technologies, including Processing, D3, WebGL and the like, which I then studied extensively on my own and am currently using in both my own research projects and in classroom (I am teaching an introductory GIS course - GEOG 160 - in Fall of 2013). As part of my coursework at PennState I also had exposure to ideas from domains of ontological modeling, database engineering for Big Data tasks, voluteered geographic information systems, language processing, data mining and crowd-sourcing, and I have published work related to a number of these topics.

I have taken classes in computer graphics, design and architecture of GIS, database systems, information storage and retrieval (natural language processing and data mining), design and analysis of algorithms (complexity analysis of algorithms, tractability of computational problems) and in theory of computation (language parsing, regular languages and grammars, finite state automata and such). I taught myself C, Dephi, Java, Python, VBA, ActionScript, JavaScript and WebGL. I have worked extensively in Processing environment and I have developed considerable expertise in all of the browser-based visualization technology, including SVG, Canvas and WebGL. I have worked with large volumes of Twitter data (reaching into terabytes) and I have used both NoSQL databases for this purpose (e.g. MongoDB) and my own software.

My dissertation research focuses specifically on the design and evaluation of cartographic techniques used to show textual data on a map. The ultimate goal of my dissertation is to design and empirically evaluate cartographic techniques that show the different conversations happening across the geographic space – topics that are representative of entire states or regions are shown similar to the way mountain chains are labeled on topographic maps, whereas local conversations that are more place-specific are shown as small “towns” on the backdrop of more global conversations. This research was inspired by both the attempts at typographic cartography I was exposed to, incliding NatGeo's What's in a Surname and wonderful work done at Axis Maps.
