AFOSR Center of Excellence in Assured Autonomy in Contested Environments
Directed by Dr. Warren Dixon - Mechanical and Aerospace Engineering (MAE) Dept.
The University of Florida (UF), Duke University (Duke), the University of Texas Austin (UTA), and the University of California Santa Cruz (UCSC) propose to establish an Air Force Office of Scientific Research (AFOSR) Center of Excellence (CoE) for Assured Autonomy in Contested Environments in collaboration with the Air Force Office of Scientific Research (AFOSR) and the munitions (RW), sensors (RY), and space vehicles (RV) directorates within the Air Force Research Laboratory (AFRL). Autonomous systems must execute high level missions plans with verifiable assurances despite uncertain adversarial environments where the integrity and availability of sensor information and communications are challenged. Key innovations include analysis, design and synthesis tools that enable autonomous mission execution despite uncertainty within complex dynamics while accounting for the integrity and privacy of information on computationally constrained resources.
To address such challenges, we develop a tightly integrated set of fundamental theories and methods across six diverse research topics.
- Modeling and Analysis Methods for Nonsmooth Systems;
- Adaptation, Optimality, and Synthesis;
- Analysis, Design and Control Synthesis Within and Over Networks;
- Design and Analysiswith Asynchronous Information;
- Attack-Resilient Designs;
- Protecting Safety- and Mission-Critical Information.
The Center of Excellence addresses many areas of direct relevance to collaborating researchers within AFRL: (space) situational awareness; sensing and communication latency/intermittency; information provenance and integrity; private computation and communication; and collaborative effects resulting from agent coordination/disaggregation in a network and over complex network channel dynamics.
Biosecurity Research & Extension (BRE) Lab @ UF IFAS
Directed by Dr. Amanda Hodges - Entomology & Nematology (EntNem) Dept.
BRE focuses on entomology, crop-based pest management, and invasive species biology.
The BRE lab critically addresses invasive arthropod issues in Florida from a cross-commodity perspective. Although many areas of Florida are urban, agricultural production and exports continue to be a vital and critical component of Florida’s economy. Approximately 9.25 million acres of Florida land is managed by over 47,500 commercial farms. In terms of U.S. production, Florida continues to rank #1 in cash receipts for numerous fruit and vegetable crops. Florida ranks #2 nationally in the production of greenhouse and nursery crops. Total crop cash receipts in 2011 were $6.8 billion. In the U.S., Florida ranks as #7 nationally in agricultural exports, with a cash value of around $4 billion.
Invasive species and agricultural biosecurity topics are increasingly important for professionals working in agricultural and natural area disciplines. In Florida, approximately two to three new insect and related arthropod species are detected every month. Florida’s subtropical to tropical climate is favorable for the establishment of many non-native arthropods. Trade and travel patterns in recent years have resulted in an increased occurrence of non-native pest arthropods in Florida and the continental U.S. Research and extension programs in our laboratory focus on:
- Improving predictions of pest potential;
- Promoting the early detection of exotic, invasive species;
- Pest management, diagnostic, and invasive species research related to Hemipteran insects.
All BRE projects are focused on immediate grower or stakeholder needs, and research results are often delivered to clientele through extension publications, meetings, or other appropriate products.
Example projects have included monitoring and biological control of an emerging population of the brown marmorated stink bug, Halyomorpha halys, within different cropping systems in Florida. Pest monitoring for both native and emerging invasive species within various crops, such as peach, grape, tomato, sorghum, peanut, soybean, cotton, and tobacco. Quarantine laboratory-based research related to pest establishment questions has also occurred.
The Bureau of Economic and Business Research (BEBR)
Directed by Dr. Christopher McCarty - Anthropology (Anthro) Dept.
Florida’s Data at Your Fingertips
BEBR produces Florida’s official state and local population estimates and projections. These estimates and projections are used for distributing state revenue-sharing dollars to cities and counties in Florida and for budgeting, planning and policy analysis by state and local government agencies, businesses, researchers, the media, and members of the general public.
BEBR was founded in 1930 and is part of the UF College of Liberal Arts and Sciences. and has been a source of Florida data for decades.
BEBR published the Florida Statistical Abstract each year from 1967 to 2011. This award-winning research volume of statistical data about Florida is the leading source of data on Florida and its cities and counties, providing information on population, housing, employment, income, education, health, tourism, elections, and much more.
Continuing in this tradition, we offer data on a variety of topics for the state and various geographic regions within the state, as well as data outside of Florida. In addition to free population and consumer sentiment data, our data services staff can help with existing secondary data from other sources and organizations. We offer data search, data processing, and data analysis services.

Areas of focus include:
The Mulligan (Human Genetics) Lab
Directed by Dr. Connie J. Mulligan - Anthro Dept.
The Mulligan Lab analyzes genetic variation in order to investigate genetic contributions to health and disease and to reconstruct human evolutionary history. In order to understand complex disease, we take a biocultural approach. We investigate genetic (candidate genes and genetic ancestry), epigenetic (specific genes and genome-wide), biological (blood pressure, biomarkers), psycho-social (stress exposures, anxiety, depression) and socio-cultural (discrimination experiences, personal social networks) data in order to create the most comprehensive picture of blood pressure variation (African Americans living in Tallahassee, FL) and the impact of stress on health outcomes (new mothers and their newborns in the Democratic Republic of Congo) and genetic and epigenetic signatures of stress and trauma (Syrian refugees in Jordan). For the study of population history, we assay genetic variants in the mitochondrial genome, autosomes and sex chromosomes, and ancient DNA in order to provide the most complete representation of human evolution.
We are particularly interested in the first migrations of anatomically modern humans out of Africa as well as the recent colonization of the New World. We study populations from around the world with an emphasis on the Arabian Peninsula, Horn of Africa, Mongolia and the New World for our population history studies and the continental US, Democratic Republic of Congo and Jordan for our disease studies.
Current research @ The Mulligan Lab includes:
- Biocultural investigations of human health and disease;
- Genetic and sociocultural risk factors for hypertension in African-Americans;
- Effect of genetic variants, trauma exposures, and resilience on psychosocial stress and mental health in Syrian refugee youth living in Jordan;
- Association of epigenetic alterations, maternal prenatal stress exposure, and birth outcomes among new mothers and newborns in the Democratic Republic of Congo;
- Human Population History:
- Biocultural evolution of populations in the Arabian Peninsula and the Horn of Africa;
- Colonization of East Asia and the New World.

The Social-Cognitive & Affective Development (Ebner) Lab
Led by Dr. Natalie Ebner - Psychology (Psych) Dept.
The Social-Cognitive and Affective Development Lab conducts research on social-cognitive and affective development in adulthood using behavioral, pharmacological, and neuroimaging methodologies.
Current aging research focuses on physical and cognitive functions and psychopathology common in the elderly. Largely ignored is negative age-related change in socioemotional capacities that can adversely affect health. Adopting pharmacological, neurofeedback, and applied interventional approaches, my research targets this understudied field to determine factors that contribute to, and neurobiology that underlies, successful socioemotional aging.
Our lab pursues the long-term goal of developing viable treatments towards functional improvement in the elderly. Our work is important from a developmental perspective, qualifies general theories of memory and decision making, and has practical implications for social interactions and health in aging.
