Yuting Chen
I work with Professor Venkatesh Saligrama in the Information Systems and Sciences Lab. My research includes computer vision and statistical learning.  More specifically, we focus on video surveillance problems such as anomalous activity detection, video event retrieval and activity modeling.  We are currently developing algorithms for tasks such as counter-flow detection in airport surveillance videos, multiple people tagging and tracking and event search in airborne surveillance videos. We are trying to solve large-scale problems with simple features, efficient data indexing structure and robust post-processing methods in real time.

I work with Professor Caramanis to develop a revised day-ahead energy market design that includes flexible, demand-side resources as well as variable generation.  Under the current market structure, both variable generation and demand-side resources do not have incentives to bid their true costs and this biases the market clearing away from the social optimum.  Our proposed design creates appropriate incentives for both participants to bid their respective costs, leading to a socially optimal equilibrium.  I am also working with Professor Caramanis and external team members on a project investigating the benefits of transmission switching in wholesale energy markets.  Initial investigations show that disconnecting certain transmission lines can lead to large savings in production costs.  To that end, we are developing algorithms to identify a set of candidate lines for disconnecting and to quickly select the “best” subset of lines to switch off, while maintaining feasibility of the transmission system.

I work in the Hybrid Networks Systems (HyNeSs) lab with Calin Belta and Mac Schwager on formal synthesis algorithms that involve information that is a priori unknown.  I am integrating techniques in information theory and machine learning with formal methodology to enrich control policies synthesized from specification languages to be able to handle tasks that involve “uncertain” specifications such as exploration or communication.  Ultimately, I plan to use this approach to establish a framework for autonomous, decentralized coordination of teams of mobile robots.

My research interests are Network Economics and Wireless Spectrum Management, particularly areas of Dynamic Spectrum Access and Secondary Spectrum Markets, both of which introduce a new way of regulating the telecommunications radio spectrum more efficiently. My current work focuses on analyzing pricing strategies and predicting possible market equilibria when multiple Wireless Spectrum Providers compete and consequently force each other to suboptimal outcomes. This involves the use of statistical tools such as Continuous Time Markov Processes, Dynamic Programming and Linear Optimization as well as the economics field of Game Theory.

Yasaman Khazaeni
I work in the CODES lab with Professor Cassandras. I work in the area of cooperative control. I use the receding horizon method for solving the data harvesting and reward collection problem in sensor networks. My work focuses on optimizing a multiple agent mission in collecting data from many static data generator points. In the optimization problem I try to minimize the total traveling time by the agents while collecting and delivering the data. I use Matlab simulation and will implement the final algorithm on actual robots in our lab.

Julia Lima Fleck
I work in the CODES Lab where our research interests encompass the design and control of discrete event and hybrid systems. Given that estimating the performance of Stochastic Hybrid Systems (SHS) is a difficult task, we seek to approximate the relationship between performance metrics and control/design parameters of such systems through the use of Infinitesimal Perturbation Analysis (IPA). We are currently evaluating the many issues involved in applying IPA to Stochastic Flow Models (SFM), which constitute a class of SHS where the time-driven dynamics are captured by flow dynamics and the event-driven dynamics are represented by switches that alter the system’s flow dynamics. In particular, we are working on the problem of threshold-based buffer control, for which IPA can be used to optimally determine the threshold value.

Xuchao Lin
We design an optimal control framework for persistent monitoring problems where the objective is to control the movement of mobile nodes to minimize an uncertainty metric in a given mission space. For a single agent in a one-dimensional space, we show that the optimal solution is obtained in terms of a sequence of switching locations, thus reducing it to a parametric optimization problem. Using Infinitesimal Perturbation Analysis (IPA) we obtain a complete solution through a gradient-based algorithm. We also propose two receding horizon controllers that are capable of obtaining a near-optimal solution on-the-fly.

My research interests lie in the field of Computational Biology and Bioinformatics with emphasis on Proteomics, and my current research focuses particularly on Protein-protein docking and Prediction of protein structure. My job involves with different fields of science such as Molecular Biology, Statistical Physics, Molecular Dynamics, and various mathematical tools such as Nonlinear Optimization. I am working on the development of new, efficient methods to predict and analyze the protein-protein interactions that play a crucial role in various aspects of the structural and functional organization of the cell.

Feng Nan
I’m interested in supervised machine learning under budget constraint. As machine learning algorithms become increasingly pervasive in big data analytics, computation and feature acquisition costs begin to play critical roles in real life applications. My research focuses on designing efficient algorithms that reduce such costs. An application area is active sensing, where the aim is to balance classification accuracy and the cost of taking sensor measurements.

Elli Ntakou
I am working with Prof. Caramanis on the extension of Locational Marginal Prices to distribution level networks to (i) incorporate marginal costs of real and reactive power, losses, voltage control and distribution asset life degradation and (ii) enable medium and low voltage consumers and distributed generation to provide reactive power compensation, voltage control and loss reduction. Today’s average cost pricing practice deprives millions of consumers from the opportunity to match their preferences to distribution system marginal costs and wastes the opportunity to capture significant cost reducing efficiencies and to assist the cost efficient integration of clean distributed generation. Recent critical developments in communication, computation, the advent of flexible loads and power electronics, advocate a major power market reform. We propose a complete market framework that optimizes costs minus distributed participant utility subject to full AC load flow relations and that includes distributed participant costs and benefits and models degrees of freedom ranging from the ability to delay and reschedule consumption to putting excess power electronics resources to dual use for VAr compensation. Addressed issues include the non-convexities of the AC load flow, computational complexity, the resulting clearing prices and distribution network rent, distributed generation optimal location and income, market size, and distributed ways for market clearing.

Sepideh Pourazarm
I work in the CODES lab under supervision of Prof. Christos Cassandras. My research interest is modeling and  optimization of energy-aware systems. More specifically, I work on optimal routing in Wireless Sensor networks.  We are developing an optimal control approach to solve the  problem of routing in sensor networks where the goal is to minimize the network’s lifetime. In our analysis, the energy sources (batteries)   are assumed ‘non-ideal’ and behaving according to a dynamic energy consumption model which captures the nonlinear behavior of actual batteries. Another problem I am working on is optimal routing of Electric Vehicles with energy constraints. In this problem, we seek to minimize the total elapsed times for EVs to reach their destinations by determining routs as well as recharging amounts when the vehicles do not have  adequate energy for the entire journey.

I work in the NISLAB on costumers’ behavior analysis of different queueing systems that support advance reservations. Our goal is to have a better understanding of the economic aspects of those systems. In particular, we are interested in finding for which settings, enabling advance reservation will increase the providers profit and/or the social welfare. We focus on  applications in the field of communication networks and cloud computing though our results can be applied to other fields. The tools we are using are Game Theory, Linear and Non-Linear Optimization, Stochastic Process and Dynamic Programming.

I am working with Professor Cassandras in the CODES Lab and our research interests are coverage control and optimization problems. We seek to use distributed algorithms to control the deployment of sensor nodes to maximize the coverage quality in a mission cluttered with obstacles. Currently, we are focusing on finding efficient algorithms to escape a local optimum in the coverage control problem. We test our algorithm by java simulation now and will do it with real robots in the lab.

Cristian-loan Vasile
I work in the Hybrid and Networked Systems Lab with Calin Belta. My research is focused on motion planning for high dimensional robotic systems which must satisfy rich mission specifications. The specifications are given as linear temporal logic formulae and are defined over propositions assigned to regions of interest in a given environment. We approach such problems using sampling based methods, a class of randomized algorithms, which are capable of rapidly exploring high dimensional spaces, and combine them with automata based model checking methods. My goal is to develop a framework for automatic deployment of robotic teams which need to cooperate in order to perform persistent tasks under communication and charging constraints.

My research lies in the area of smart grid. I explore the possibility to schedule electricity consumption for both residential and commercial buildings where smart appliances have been adopted. Thermostatic appliances is open to demand response since the thermostatic points could be adjusted to electricity prices and temperature could be controlled within comfortable zone with predetermined policies. The smart grid research is correlated with multi-disciplinary knowledge such as dynamic programming, optimization, queuing system, and control theory. Our research also deals with the system identification of electric consumption pattern in actual buildings. We are going to deploy some current transformers to monitor the electric consumption pattern of 15 St. Mary’s, both steady state electric power flow and transient performance would be studied once the data from current transducers are collected. Aside from the issues discussed above, we are also interested in the planning of reserve selling, peak demand consumption shifting, etc.

I am working with Professor Yannis Paschalidis in the Network Optimization and Control Lab. The first research lies in the health care area. It aims to model the effect of Bivalirudin (a medicine used in cardiac surgical patients in ICU) and then make the automatic dosage decision based on the model and data we have. This project involves nonlinear optimization, machine learning, adaptive control theory and so on. The second research topic lies in the biology area. The objective is to infer the real objective function of bacteria. This is an inverse optimization problem that we need to infer the objective function based on the optimal solution we have.
