Research
We live in a highly interdependent and increasingly vulnerable world. Decisions made at one corner of the world
often produce upheaval on unsuspected lives at another corner. Seemingly innocuous actions carried out in
everyday life are leading to long lasting and adverse consequences, both to the present and the coming generation.
Dealing with highly dynamic and complex situations requires a rich knowledge and penetrating understanding.
The purpose of my research is to enrich human beings with knowledge of their surroundings by
developing and deploying adaptive and resilient sensing systems. I strive to fulfill this purpose by pursuing
three complementary goals. My first goal is to develop highly adaptive and energy-efficient sensing nodes.
This includes modeling, testing, and integrating state-of-the-art sensors. My second goal is to develop efficient
and lightweight communication protocols to establish self-organizing and highly resilient distributed
and wireless sensing systems. My third goal is to apply probabilistic models and unsupervised learning in
order to extract meaning from sensed data.

Cooperation
I have been very fortunate to meet and work with many talented individuals around the world. Currently, I am collaborating closely with the following researchers:
Professor Christian Poellabauer (FIU): On impacts of cancer treatment on autonomic function.
Professor Kewei Sha (North Texas University): On the dynamic detection of sophisticated ECG tampering.
Professor Abiy Tasissa (Tufts University): On mathematical models for XAI.
Autobiography
My autobiography will be released in January 2027 worldwide.
Does a dream have a life of its own? How long does it last? What part of it remains intact, surviving the turbulent tides of change and a multitude of indifferent existential storms? In his autobiography, Dr. Waltenegus Dargie recounts the dream he cherished in his youth: that of academic excellence, a dream shaped and tested by various influences, including family upheaval, civil war, communism, atheism, Christianity, European Epicureanism, and solitude.
"This one had become truly unattainable, becoming very much like the real object I had been waiting for my whole life. I wondered if this was what Beckett wanted to convey in Waiting for Godot. Until then, I had believed the book had something to do with Christianity and its promise of Christ’s return. Now I doubted that was the intended message. I felt he was talking about the endless wait for something unknown
and intangible."
