You can observe catalog_product_collection_apply_limitations_after event, assuming you have a product attribute to filter according your desired logic

So, in your observer...

public function yourmethod($observer){

    // here you have customer object
    $currentUser = Mage::getSingleton('customer/session')->getCustomer();

    // your logic here, so let's say you get
    // $yourFilteredValue for 'your_attribute'
    // based in $currentUser data

    // and then... the filter
    $collection = $observer->getEvent()->getCollection();
    $collection->addAttributeToFilter('your_attribute',array('eq'=> $yourFilteredValue));
}
