His research interests include developing alternative blood culture methods and rapid blood culture isolate identification assays.

Diagnostic test specificity is as much about context as it is numbers; here, we discuss pitfalls of focusing on numbers for multiplexed panel tests.

Big scientific conferences are great, but smaller meetings fill a specialized niche. The Clinical Microbiology Open is a new conference intended to drive industry-academia collaboration to address unmet or poorly met needs in the field of clinical microbiology. 

It’s Lyme Time! As summer approaches, ticks and people will meet up once again. Diagnostic tests for Lyme disease may change, but these changes should always based on scientific evidence.

Patients require care around the clock and clinical labs are a critical component of patient care. Clinical laboratory technologists work day - and night - to help make a difference.

Toxoplasma gondii is a fantastically interesting parasite that you can find in a variety of places in the world and can end up in a variety of places inside of you!

Non-culture based fungal diagnostic tests

Timely diagnosis of fungal infections is sometimes impaired by the slow growth in culture or low yield of culture for certain organisms. Let’s discuss some of the non-culture based fungal diagnostic tests that are available in clinical microbiology laboratories.

Bloodstream infections are a major cause of morbidity and mortality, and identifying the causative organism(s) is critical. Can the most important step in this process really be as simple as collecting enough volume of blood for culture? Let’s discuss some of the evidence, and the role of the clinical microbiology laboratory in this important testing process.

Clinical microbiology tests are not performed to satisfy the curiosity, but to serve patients. While technical performance comparisons will sometimes suffice for test evaluation, health outcome studies may be superior for determining the true value of a diagnostic test.
