Additional Information

Water flows downhill, sometimes water is a resource, sometimes it is an enemy, sometimes it is both. If your case involves the impact of water, my expertise is available for your case. I am an expert in hydrology, hydraulics, the engineering of drainage systems, including culverts, transportation drainage, bridge scour, bridge hydraulics, floodplain management, transportation hydraulics, water resources, and accidental death or drowning near hydraulic structures. My work routinely produces technical evidence that is hard to dispute and easy to understand. My background and experience in consulting and teaching allows me to produce complicated information in a format that is easy to digest, such as video files, and images that explain the complicated physical interactions of hydrology and hydraulics. Some of my past litigation work produced evidence that was not disputed by opposing experts. My approach is to first understand the case, then to discuss one on one what technical aspects are needed, what may be missing or is not yet discovered. I will then develop a work plan forward that often includes hydrologic and hydraulic analysis, a forensics investigation of past events and current conditions, and ultimately presentation of the results in an easy and understandable format. My professional accomplishments include multiple peer reviewed publications, board certification in water resources (DWRE), professional engineering licenses in multiple states (CO, NV, TX, WI, NM, OH, AZ, OR, KY, ND, KS), lead instructor roles for professional development, and a full time Associate Professor (Clinical Track) position at the University of Colorado Denver. My background includes work as a consulting engineer, an engineer for the federal government, and a engineer for the Army as a soldier (Construction Combat Engineer). I was honorably discharged as a veteran of foreign wars (VFW) from combat tours for OIF and OEF. I currently run my own consulting practice (Advanced Engineering and Academic Sciences), which is a Service Disabled Veteran Owned Small Business recognized by the Small Business Administration. Again, water can be our resource, our enemy, or both. If your case involves the impact of water and you need an expert, please call me at 303-514-7672.
