Ph.D. Students
Harshal Maske  
Hashal Maske Harshal Maske is a Doctoral student at Oklahoma State University with a Masters degree in Mechanical Engineering from Indian Institute of Technology Kharagpur. After completing his masters, he worked for one year at John Deere and for two years at Defense R&D Organization, India. His current research is grounded in the theory of Bayesian nonparametrics, Reinforcement learning, and Stochastic processes to enable decision making and control in real-world, complex problems, specifically autonomous co-robots, such as the Excavator project.
Allan Max Axelrod  


My career goal is to enable the use of autonomous systems in dynamic human environments.  A critical challenge to overcome is automated situational awareness in nonstationary environments.  A key aspect from my research which I expect will be instrumental in moving towards automated situational awareness is the use of models on the information injected into a partially-observable time-varying environment.

Recent Developments

This past Summer, I presented an excerpt of my masters thesis on defining a data-driven Fog of War term and on uninformed-to-informed exploration.  The presentation was received by colleagues at Leeds University, Sheffield University, Hertfordshire University, Technische Universitat Darmstadt, Boston University, and Massachusetts Institute of Technology.  

Masters Thesis

Learning to Exploit Time-Varying Heterogeneity in Distributed Sensing using the Information Exposure Rate considers the data-ferrying problem in the context of synthetic and real-world datasets where no a priori information on the datasets is available to the agent. Due to endurance constraints, the data-ferying agent must learn to prioritize reachable sensors based on their expected informatic value, quantified as Kullback-Leibler (KL) divergence. We formulate and apply Bayesian nonparametric Poisson exposure processes (Pep) for modeling the available KL divergence for each sensing location.  We also provide a probabilistic sampling bound on the accuracy of the Pep; this bound is applied in the EIEIO, RAPTOR, and DUCK algorithms, which are shown to outperform baseline methods in syntehic and real-world datasets.

Rakshit Allamraju  

Rakshit Allamraju is a Masters Student at DASLAB working with Dr.Girish Chowdhary.

His current research includes solving distributed inference for environment monitoring and event prediction using sensor networks and multiagent autonomous decision making. He is currently leading charge in developing DAS-MAGE, which is a cloud based simulation environment for testing multi-agent decision making and control algorithms.

His past research included planning and decision making under uncertainties in partially observable environments, solving Non stationary Markov decision process problems, by transitional estimations of dynamic environment, applying model based reinforcement learning techniques.  

Ali Abdollahi  

Ali Abdollahi is a Master's student in Mechanical & Aerospace Engineering department. He received one of his Bachelor's degrees in Mechanical Engineering and the other one in Biomedical Engineering. Biomechanics and numerical methods for mechanics of material analysis were his main focus in undergraduate.


He has worked on model reference adaptive control and model predictive control started by a NASA project. His other research interests consist of Gaussian Process non-Bayesian clustering application to nonstationary dynamical systems and reinforcement learning methods in time-varying Markov decision processes and contested environments.


He is currently working on risk-averse optimization and nonstationary model-based reinforcement learning algorithms for risk-averse adaptive decision making.

Alex Suhren  
  My work focuses on robotic vision systems.  I have implemented vision systems ranging from corner-detection to scale- and angle- invariant optical flow methods.  My most contributions to robotic vision are the product of an ongoing collaboration with Dr. Doug Gaffin at the University of Oklahoma wherein we're focusing on emulating, robustifying and sparsifying the vision-based navigation system of bees.

Milecia Matthews

I am working on my MS in Mechanical Engineering at Oklahoma State University.

My current research involves intent communication between pedestrians and autonomous vehicles using POMDPs to learn what actions to expect from pedestrians and how they react to requests given by the vehicle. I am also working on developing a fully autonomous robot capable of maneuvering through viscous fluids while collected data about the fluid using POMDPs.

My research interest are: autonomous vehicles, learning algorithms, and the psychology behind human and machine interactions.  

Hunter Young  

I am pursuing a Master's of Science in Mechanical and Aerospace Engineering at Oklahoma State University.

My current research involves the cooperative navigation of multi-agent systems in GPS-denied environments. The goal of this research is to allow a multi-agent (2+ robot) system to navigate from point A to point B with the robots stopping as close to the goal as possible. This will hopefully be achieved by using only the robots' heading, speed, and relative distance.

My research interests are the implementation of control theory fundamentals for the use in general robotic applications to real world problems.
